R help - Dec 2007 - names in Rscript -e

Hi, 

I seem to have a problem when passing named parameters to R via Rscript (R2.5.1,
bash shell). As soon as I name elements of a list Rscript generates an error.

I will appreciate if someone could point to me a correct way of doing this. 

Thanks, 
Vadim 

## This works 
bash-3.2$ Rscript.exe -e 'list(1)' 
[[1]] 
[1] 1 

# and these do not work 
bash-3.2$ Rscript.exe -e 'list(a=1)' 
Error in -args : invalid argument to unary operator 
Execution halted 

bash-3.2$ Rscript.exe -e 'list(\"a\"=1)' 
Error in -args : invalid argument to unary operator 
Execution halted

Never mind, it works under R2 .6.0. Sorry, for not checking it earlier . 

Thanks, 
Vadim
