Comments regarding r-cran-spdep_0.5-92-1_amd64.changes

[Thorsten Alteholz]

Hi Andreas,

the issues about src/soigraph.c are not really solved.

According to the file:
* The subroutines TwoCirclesxx and SubVec are adapted for R and Double
* precision coordinates by Nicholas Lewin-Koh, from Computational
* Geometry in C, Joseph O'Rourke, Cambridge University Press
* (1998), specifically from arm/arm.c. Copyright for those subroutines
*  remains his.

As you can see, for example on Amazon, this book contains a paragraph:

This book is in copyright. (...) no reproduction of any part may take 
place without the written permission of Cambridge University Press.

>From my point of view this does not look like that "This code may be 
freely redistributed" ...
