Unhandled SIGABRT: An abort() occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().

That behaviour is intended, since a\n decorated method appears to have the generic signature\n ``*args,**kwds``, but in fact it is only supposed to be called\n with the arguments requested by the underlying undecorated\n method. We saw an easy example above, namely ``I.groebner_basis``.\n Here is a more difficult one::\n\n sage: cython_code = [\n ....: \'cdef class MyClass:\',\n ....: \' def _sage_src_(self):\',\n ....: \' return "def foo(x, a=\\\\\\\')\\\\\\"\\\\\\\', b={(2+1):\\\\\\\'bar\\\\\\\', not 1:3, 3<<4:5}): return\\\\n"\',\n ....: \' def __call__(self, m,n): return "something"\']\n sage: cython(\'\\n\'.join(cython_code))\n sage: O = MyClass()\n sage: print(sage.misc.sageinspect.sage_getsource(O))\n def foo(x, a=\')"\', b={(2+1):\'bar\', not 1:3, 3<<4:5}): return\n sage: spec = sage.misc.sageinspect.sage_getargspec(O)\n sage: spec.args, spec.varargs, spec.keywords\n ([\'x\', \'a\', \'b\'], None, None)\n sage: spec.defaults[0]\n \')"\'\n sage: sorted(spec.defaults[1].items(), key=lambda x: str(x))\n [(3, \'bar\'), (48, 5), (False, 3)]\n sage: sage.misc.sageinspect.sage_getargspec(O.__call__)\n ArgSpec(args=[\'self\', \'m\', \'n\'], varargs=None, keywords=None, defaults=None)\n\n ::\n\n sage: cython(\'def foo(x, a=\\\'\\\\\\\')"\\\', b={not (2+1==3):\\\'bar\\\'}): return\')\n sage: print(sage.misc.sageinspect.sage_getsource(foo))\n def foo(x, a=\'\\\')"\', b={not (2+1==3):\'bar\'}): return\n <BLANKLINE>\n sage: sage.misc.sageinspect.sage_getargspec(foo)\n ArgSpec(args=[\'x\', \'a\', \'b\'], varargs=None, keywords=None, defaults=(\'\\\')"\', {False: \'bar\'}))\n\n The following produced a syntax error before the patch at :trac:`11913`,\n see also :trac:`26906`::\n\n sage: sage.misc.sageinspect.sage_getargspec(r.lm)\n ArgSpec(args=[\'self\'], varargs=\'args\', keywords=\'kwds\', defaults=None)\n\n The following was fixed in :trac:`16309`::\n\n sage: cython(\'\'\'\n ....: class Foo:\n ....: @staticmethod\n ....: def join(categories, bint as_list = False, tuple ignore_axioms=(), tuple axioms=()): pass\n ....: cdef class Bar:\n ....: @staticmethod\n ....: def join(categories, bint as_list = False, tuple ignore_axioms=(), tuple axioms=()): pass\n ....: cpdef meet(categories, bint as_list = False, tuple ignore_axioms=(), tuple axioms=()): pass\n ....: \'\'\')\n sage: sage_getargspec(Foo.join)\n ArgSpec(args=[\'categories\', \'as_list\', \'ignore_axioms\', \'axioms\'], varargs=None, keywords=None, defaults=(False, (), ()))\n sage: sage_getargspec(Bar.join)\n ArgSpec(args=[\'categories\', \'as_list\', \'ignore_axioms\', \'axioms\'], varargs=None, keywords=None, defaults=(False, (), ()))\n sage: sage_getargspec(Bar.meet)\n ArgSpec(args=[\'categories\', \'as_list\', \'ignore_axioms\', \'axioms\'], varargs=None, keywords=None, defaults=(False, (), ()))\n\n Test that :trac:`17009` is fixed::\n\n sage: sage_getargspec(gap)\n ArgSpec(args=[\'self\', \'x\', \'name\'], varargs=None, keywords=None, defaults=(None,))\n\n By :trac:`17814`, the following gives the correct answer (previously, the\n defaults would have been found ``None``)::\n\n sage: from sage.misc.nested_class import MainClass\n sage: sage_getargspec(MainClass.NestedClass.NestedSubClass.dummy)\n ArgSpec(args=[\'self\', \'x\', \'r\'], varargs=\'args\', keywords=\'kwds\', defaults=((1, 2, 3.4),))\n\n In :trac:`18249` was decided to return a generic signature for Python\n builtin functions, rather than to raise an error (which is what Python\'s\n inspect module does)::\n\n sage: import inspect\n sage: inspect.getargspec(range) # py2\n Traceback (most recent call last):\n ...\n TypeError: <built-in function range> is not a Python function\n sage: sage_getargspec(range)\n ArgSpec(args=[], varargs=\'args\', keywords=\'kwds\', defaults=None)\n\n Test that :trac:`28524` is fixed::\n\n sage: from sage.repl.interpreter import get_test_shell\n sage: shell = get_test_shell()\n sage: shell.run_cell(\n ....: \'class Foo:\\n\'\n ....: \' def __call__(self):\\n\'\n ....: \' return None\\n\'\n ....: \' def _sage_src_(self):\\n\'\n ....: \' return "the source code string"\')\n sage: shell.run_cell(\'f = Foo()\')\n sage: shell.run_cell(\'f??\')\n ...the source code string...\n\n AUTHORS:\n\n -

Integer(x=None, base=0)
File: sage/rings/integer.pyx (starting at line 438)
The ``Integer`` class represents arbitrary precision
integers. It derives from the ``Element`` class, so
integers can be used as ring elements anywhere in Sage.
Integer() interprets strings that begin with ``0o`` as octal numbers,
strings that begin with ``0x`` as hexadecimal numbers and strings
that begin with ``0b`` as binary numbers.
The class ``Integer`` is implemented in Cython, as a wrapper of the
GMP ``mpz_t`` integer type.
EXAMPLES::
sage: Integer(123)
123
sage: Integer("123")
123
Sage Integers support :pep:`3127` literals::
sage: Integer('0x12')

------------------------------------------------------------------------
Unhandled SIGABRT: An abort() occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.

Unhandled SIGABRT: An abort() occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.

Welcome to Sage 9.0!
To view the Sage tutorial in your web browser, type "tutorial()", and
to view the (very detailed) Sage reference manual, type "manual()".
For help on any Sage function, for example "matrix_plot", type
"matrix_plot?" to see a help message, type "help(matrix_plot)" to see
a very similar message, type "browse_sage_doc(matrix_plot)" to view a
help message in a web browser, and type "matrix_plot??" to look at the
function's source code.
(When you type something like "matrix_plot?", "help(matrix_plot)", or
"matrix_plot??", Sage may start a paging program to display the
requested message. Type a space to scroll to the next page, type "h"
to get help on the paging program, and type "q" to quit it and return
to the "sage:" prompt.)
For license information for Sage and its components, read the file
"COPYING.txt" in the top-level directory of the Sage installation,
or type "license()".
To enter Python's interactive online help utility, type "python_help()".
To get help on a Python function, module or package, type "help(MODULE)" or
"python_help(MODULE)".

regression
description
***********
lm is used to fit linear models.
It can be used to carry out regression, single stratum analysis of
variance and analysis of covariance (although aov may provide a
more convenient interface for these).
usage
*****
lm(formula, data, subset, weights, na.action,
method = "qr", model = TRUE, x = FALSE, y = FALSE, qr = TRUE,
singular.ok = TRUE, contrasts = NULL, offset, )
arguments
*********
formula an object of class " formula " (or one that
can be coerced to that class): a symbolic description of the
model to be fitted. The details of model specification are
given under Details .
data an optional data frame, list or environment (or object
coercible by as.data.frame to a data frame) containing the
variables in the model. If not found in data , the variables
are taken from environment(formula) , typically the environment
from which lm is called.
subset an optional vector specifying a subset of observations
to be used in the fitting process.
weights an optional vector of weights to be used in the fitting
process. Should be NULL or a numeric vector. If non-NULL,
weighted least squares is used with weights
weights (that is, minimizing sum(w*e^2) ); otherwise
ordinary least squares is used. See also Details ,
na.action a function which indicates what should happen
when the data contain NA s. The default is set by the
na.action setting of options , and is
na.fail if that is unset. The factory-fresh
default is na.omit . Another possible value is
NULL , no action. Value na.exclude can be useful.
method the method to be used; for fitting, currently only
method = "qr" is supported; method = "model.frame" returns
the model frame (the same as with model = TRUE , see below).
model, x, y, qr logicals. If TRUE the corresponding
components of the fit (the model frame, the model matrix, the
response, the QR decomposition) are returned.
singular.ok logical. If FALSE (the default in S but
not in ) a singular fit is an error.
contrasts an optional list. See the contrasts.arg
of model.matrix.default .
offset this can be used to specify an a priori known
component to be included in the linear predictor during fitting.
This should be NULL or a numeric vector or matrix of extents
matching those of the response. One or more offset terms can
be included in the formula instead or as well, and if more than
one are specified their sum is used. See model.offset .
additional arguments to be passed to the low level
regression fitting functions (see below).
details
*******
Models for lm are specified symbolically. A typical model has
the form response ~ terms where response is the (numeric)
response vector and terms is a series of terms which specifies a
linear predictor for response . A terms specification of the form
first + second indicates all the terms in first together
with all the terms in second with duplicates removed. A
specification of the form first:second indicates the set of terms
obtained by taking the interactions of all terms in first with all
terms in second . The specification first*second indicates the
cross of first and second . This is the same as first +
second + first:second .
If the formula includes an offset , this is evaluated and
subtracted from the response.
If response is a matrix a linear model is fitted separately by
least-squares to each column of the matrix.
See model.matrix for some further details. The terms in the
formula will be re-ordered so that main effects come first,
followed by the interactions, all second-order, all third-order and
so on: to avoid this pass a terms object as the formula (see
aov and demo(glm.vr) for an example).
A formula has an implied intercept term. To remove this use either
y ~ x - 1 or y ~ 0 + x . See formula for
more details of allowed formulae.
Non- NULL weights can be used to indicate that different
observations have different variances (with the values in
weights being inversely proportional to the variances); or
equivalently, when the elements of weights are positive integers
w_i , that each response y_i is the mean of
w_i unit-weight observations (including the case that there
are w_i observations equal to y_i and the data have been
summarized). However, in the latter case, notice that within-group
variation is not used. Therefore, the sigma estimate and residual
degrees of freedom may be suboptimal; in the case of replication
weights, even wrong. Hence, standard errors and analysis of
variance tables should be treated with care.
lm calls the lower level functions lm.fit , etc,
see below, for the actual numerical computations. For programming
only, you may consider doing likewise.
All of weights , subset and offset are evaluated in the same
way as variables in formula , that is first in
data and then in the environment of formula .
value
*****
lm returns an object of class "lm" or for
multiple responses of class c("mlm", "lm") .
The functions summary and anova are used to obtain and print a
summary and analysis of variance table of the results. The generic
accessor functions coefficients ,
effects , fitted.values and residuals extract
various useful features of the value returned by lm .
An object of class "lm" is a list containing at least the
following components:
coefficients a named vector of coefficients residuals the
residuals, that is response minus fitted values. fitted.values
the fitted mean values. rank the numeric rank of the fitted
linear model. weights (only for weighted fits) the specified
weights. df.residual the residual degrees of freedom. call the
matched call. terms the terms object used. contrasts (only
where relevant) the contrasts used. xlevels (only where
relevant) a record of the levels of the
factors used in fitting.
offset the offset used (missing if none were used). y if
requested, the response used. x if requested, the model matrix
used. model if requested (the default), the model frame used.
na.action (where relevant) information returned by
model.frame on the special handling of NA s.
In addition, non-null fits will have components assign ,
effects and (unless not requested) qr relating to the linear
fit, for use by extractor functions such as summary and
effects .
section
*******
Using time series
Considerable care is needed when using lm with time series.
Unless na.action = NULL , the time series attributes are stripped
from the variables before the regression is done. (This is
necessary as omitting NA s would invalidate the time series
attributes, and if NA s are omitted in the middle of the series
the result would no longer be a regular time series.)
Even if the time series attributes are retained, they are not used
to line up series, so that the time shift of a lagged or
differenced regressor would be ignored. It is good practice to
prepare a
data argument by ts.intersect ( , dframe = TRUE) ,
then apply a suitable na.action to that data frame and call
lm with na.action = NULL so that residuals and fitted
values are time series.
note
****
Offsets specified by offset will not be included in predictions
by predict.lm , whereas those specified by an offset term in the
formula will be.

described in Chambers (1992). The implementation of model formula
by Ross Ihaka was based on Wilkinson & Rogers (1973).
