Hi,
I installed latest R on fresh Windows 10, then I installed several
packages into my personal library, then I installed standalone GRASS
GIS 7.3, and when I run R from GRASS session, it does not see the
installed packages. .libPaths() called from GRASS session indeed does
not show the path to the personal library. I installed the packages
again in GRASS session and then it's OK. Any idea why this happens and
how to avoid that?
No idea, only you can reproduce what you are doing. Do you mean 7.3, the
development version? Try the 7.0 and 7.2 versions, and compare to see
which environment variables may not be being transferred (R_LIBS probably)
in GRASS 7.3. Are you running R in a Windows terminal (if such
exists in Windows 10) inside GRASS, or in the command line in the
GRASS GUI? If the latter, has this changed?

You would need to try to load a package from your personal library, so:
.libPaths()
library()
installed.packages()
should show whether anything is found, and to install within the GRASS
session:
install.packages("rgrass7")
library(rgrass7)
and see what happens.
For me on Linux, R_LIBS is set by me and works, but on Windows the default
is (possibly) set in the Registry anyway, which would/should be used if
R_LIBS is not set. Within R, .libPaths() should be the same inside GRASS
and outside GRASS. In Linux I have chosen to set R_LIBS, in Windows 7,
GRASS standalone 7.0.4, I can start R GUI in the GRASS GUI console command
line, and my personal library is found (no R_LIBS set, .libPaths() returns
the default). I haven't tried with GRASS 7.2 on Windows.
