[R-pkg-team] Bug#939002: Problem in test suite of sf since upgrade of proj

[Edzer Pebesma]

Thanks for reporting.

I see warnings of this kind:

< Warning message:
< In CPL_crs_from_proj4string(x) :
<   GDAL Message 1: +init=epsg:XXXX syntax is deprecated. It might
return a CRS with a non-EPSG compliant axis order.

but not the errors you get with +init=epsg:xxxx ; this is with PROJ
6.1.1RC1, and now with PROJ 6.2.0. I have no idea why.
