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
R GUI:
parseGRASS("r.flip")
Command: r.flip
Extension: .exe
Description: Flips an image.
Keywords: Flips an image.
Parameters:
name: input, type: string, required: yes, multiple: no
keydesc: name, keydesc_count: 1
[Name of input raster map]
name: output, type: string, required: yes, multiple: no
keydesc: name, keydesc_count: 1
[Name for output raster map]
Flags:
name: w [East-West flip] {FALSE}
name: b [Both N-S and E-W flip] {FALSE}
name: overwrite [Allow output files to overwrite existing files] {FALSE}
name: help [Print usage summary] {FALSE}
name: verbose [Verbose module output] {FALSE}
name: quiet [Quiet module output] {FALSE}
and
Sys.getenv("PATH")

If I remove this folder, the:

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
workaround is to install any extension before starting R in GRASS.

Dear ALL
I installed new GRASS GIS 7.0 (stable) and R (last versions + all packages
were updated).
Then started R (also tried Rstudio) from GRASS as it is recommended here:
https://grasswiki.osgeo.org/wiki/R_statistics/rgrass7
R started, but when I tried to load libraries I got the following error
and nothing works:
-------------
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’
library(rgdal)
rgdal: version: 1.1-10, (SVN revision 622)
Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 2.0.1, released 2015/09/15
Path to GDAL shared files: C:/Users/Andriy/R/win-library/3.3/rgdal/gdal
Loaded PROJ.4 runtime: Rel. 4.9.2, 08 September 2015, [PJ_VERSION: 492]
Path to PROJ.4 shared files: C:/Users/Andriy/R/win-library/3.3/rgdal/proj
Linking to sp version: 1.2-3
G <- gmeta()
Error: could not find function "gmeta"
-----------
However if I just start R alone (not from GRASS) the packages are loaded
normally without errors (of course if I start R not from Grass I can't
use Grass data).
I tried older versions: Grass 6.4.2 works with R fine, but not GRASS 7.
Tried on 3 different PCs. Same problem.
Could you please help to fix it?
Thank you.
Andrew
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.

best regards
Helmut
