R help - Jan 2008 - double-click in RData file versus load( file )

hello all,

when I start up the R and I execute o follow code:

 > ls()
character(0)
 > x=123
 > assign("test_x", x, envir = .GlobalEnv )
 > ls()
[1] "test_x" "x"     
 > setwd('C:\\R\\etc')
 > save.image('TEST.RData')
 > q('no')

I have two different behaviours:

(a) - when I start up R again by "double click" in the file
TEST.RData;
(b) - when I start up R and load the file TEST.RData by window menu in 
Rgui or
invoke by command ' load('C:\\R\\etc\\TEST.RData')


In case (a): I can't see my previous variables anymore!
 > ls()
character(0)


In case (b): I get my previous variables again!
 > load('C:\\R\\etc\\test.rdata')
 > ls()
[1] "test_x" "x"    
 >

Is it the correct behaviour?
the two way don't must be the same?


Thank for explanations...

Cleber Borges

Which version of R are you using?  It works fine for me in 2.6.1.

What do you see when R starts?  It should display something like

and the last line indicates the attempt to load the saved data.

When you double click it does it start up the same version of R
as when you manually start R?

If you manually start R, load it, save it under another name and
then exit R and double click the new name does that work?

hello Gabor,

the result in combobox is:

R version 2.6.1 (2007-11-26) - C:\R

I not have Perl installed! I remember that I deleted it!

OK.  The system only knows about one R version.

What about the answer to my original second question.
If you start up R and then load the .Rdata file (which you
previously indicated works) and then
save your workspace using a different name from the original
Rdata file and then double click on that new Rdata file does
that get you the variables in the new Rdata file?

hi Duncan,

I can't access file greater than 3 mb in my work! :-( :-(
((( unfortunately, is not a joke! I need a new job :-D )))

When I return home, I will do download the patch and
 report the results to you!  :-(


Thanks for your attention!

Cleber
