Re: [GRASS-stats] GRASS GIS 7.0 (stable) and R integration issue

I've put a Windows binary and source of rgrass7_0.1-9 on:


http://spatial.nhh.no/R/rgrass7/

which I believe resolves the issue. Please test and report back (on list,subscribe first, then reply or post). Please also check with addonspresent to be sure that the fix works both with and without addons.

Hi,

Thanks for helping resolve this.

I have 3 addons seen in Settings -> Addon extensions -> Manage ...
I reinstalled them, so for example .../bin/r.flip.exe has current time. In RGUI:
 parseGRASS("r.flip")

and directly:
 Sys.getenv("GRASS_ADDON_BASE")

If I remove this folder, the:
 library(rgrass7)
Loading required package: sp
Loading required package: XML
Error : .onAttach failed in attachNamespace() for 'rgrass7', details:
  call: if (class(t0) != "try-error" && is.character(t0) && nchar(t0) >
  error: missing value where TRUE/FALSE needed
Error: package or namespace load failed for ‘rgrass7’
error becomes replicable. I'll report back when I've fixed it; the workaroundis to install any extension before starting R in GRASS.

after starting R in winGRASS and before library("rgrass7") , could you do:sessionInfo()have you installed any GRASS addons? if yes, which one?
 the addons are installed in C:\Users\yourusername\AppData\Roaming\GRASS7

 if you have installed some GRASS addons, could you delete the addons
 folder
 in the C:\Users\yourusername\AppData\Roaming\GRASS7

 then restart winGRASS (without any addons installed) and R and try to do
library("rgrass7") again and report the results.
