[R-sig-Geo] Error in CRS("EPSG:4326") : no arguments in initialization list

[Roger Bivand]

Tom,

Your package code itself runs lots of stuff in R/AAA.R that it doesn't 
need to. Here you could simply put the output string of:

> rgdal::CRSargs(sp::CRS("EPSG:4326"))
[1] "+proj=longlat +datum=WGS84 +no_defs"

instead of going out to sp/rgdal/PROJ. In this case, sp and rgdal 
shouldn't let you do this on a system running PROJ 5.2.0 (and I'll look at 
that), but your work-around is the bare Proj4 string, which is the same in 
any case. The error message is from PROJ, returned from rgdal to sp. If 
you want to condition on PROJ version, you can do that, but instantiating 
CRS is costly, and here lazy-loading is trying to save time by 
pre-filling the value.

If this isn't enough, please let me know and I'll install the same PROJ 
and GDAL versions as used for Solaris checks locally, and try to resolve 
the problem in those packages. That will however take time. I'm assuming 
that sp and rgdal are the current CRAN versions 1.4-5 and 1.5-23 on 
Solaris, both of those pass on that platform.

Hope this helps,

Roger
