Hi,

anybody know any way to make a bash script to start Rcmdr directly widthout 
need to open R and execute library(Rcmdr)?

I try to make this using R CMD BATCH somethink, but dont find the way.

Thanks
Ronaldo

Dear Ronaldo,

You should be able to put

local({
old <- getOption("defaultPackages")
options(defaultPackages = c(old, "Rcmdr"))
})

in an .Rprofile file in a directory reserved for this purpose, and have your
bash script start R from that directory (untested). See ?Startup for details
on how R starts.

I hope this helps,
 John

For some reason, Rcmdr requires an interactive session:

gannet% Rscript -e 'library(Rcmdr)'
Loading required package: tcltk
Loading Tcl/Tk interface ... done
The Commander GUI is launched only in interactive sessions

However, I was able to do

gannet% cat foo
#!/bin/sh
R_DEFAULT_PACKAGES=Rcmdr R

Probably you need R in interactive mode to respond to the Tcl/Tk callbacks 
(and not just terminate when no input is found).

$ r -lRcmdr -e'while(TRUE) Sys.sleep(1)'

where r is the binary from our littler tool.  This loads the Rmcdr
package with the -l | --library switch abnd then evals a simple loop
to keep running.  You need to kill that loop with Crtrl-c at the end.
