Dear all:
Do you have any suggestions on this? Thank you.
I cannot type in the GRASS GUI with MSYS window and execute commands. It is
frozen, and when I open up another GRASS console and type R the console
says: "R is not recognizable as an internal or external command,
operable program or batch file."
I provide examples below. Roger has been helpful, but I am still unsure if I am \
missing something, or there is a bug.
I have found bugs in other programs, e.g., WinRhizo, but I am assuming GRASS is \
working fine. I have been looking for screenshot instructions to better understand my \
issue, so anyone knows of these posted somewhere, this would be helpful.

I. My main point of confusion is that when I type the path into GRASS
MSYS, the R console window pops up, and I am unable to type more into
the GRASS console. I cannot type GRASS commands in R, so I am unsure
where I type the GRASS commands if GRASS console does not let me type
more, and the R console does not recognize R commands.
Why should
it? Simply minimise the R GUI to work in GRASS directly, using the
GRASS GUI or from the prompt in MSYS. I doubt very much whether saying
d.ask makes sense anyway, as the GRASS display GUI covers that.
It
is possible to write GRASS commands using execGRASS() from the R
console, but since you have had to ask, you will find it easier simply
to minimise R and use GRASS directly. Because R is within GRASS, it
"sees" the current status of the location.
Hope this clarifies - please change to one of the GRASS lists for further help.

1. Within the GRASS 6.4.2RC2 with MSYS, I typed using tab
autocompletion: "C:/Program Files/R/R-2.14/bin/i386/Rgui.exe" which
causes the RGui to pop up as a second R window. Thus, I am not in GRASS
directly anymore I assume, but rather in the RGui. In this GUI, it says
the following when I type library(spgrass6): "GRASS GIS Interface loaded
with GRASS version GRASS 6.4.2RC2exported (2011) and location:
demolocation" gmeta6() gisdbase C:/Documents etc.

2. I can also get this to work in R directly: loc <-
initGRASS("C:/Program Files/Grass 6.4",home=tempdir()) gmeta6() **prints
gisdbase, etc.**
