[R] some related problems

I just tried to batch-start rgui.exe (not rterm.exe) in a way, that it
read.table()s data from a file with changing filename. As I understand no
command line parameters are available for that, so instead I tried to pass
the filename to an approbriate .RProfile, which works roughly, BUT

## this is my %R_USER%\.RProfile
im <- read.table("d:/temp/im/temp.csv", header=TRUE, sep=",")
nam <- names(im)
nnam <- nchar(nam)
newnam <- substr(nam, 2, nnam-1) # change names from e.g. <"x"> to <x>
names(im) <- newnam
pairs2(im)
## end

Two lines in this code do not work *during* .RProfile execution, but they
work if entered manually *after* all profile executions:

names(im) <- newnam  # should work always
Error: attempt to set an attribute on NULL

pairs2(im) # my global RProfile sources a file which defines pairs2()
Error: couldn't find function "pairs2"

How can I make these commands working during .RProfile execution?
Moreover: how can I exchange single Backslashes to slashes in R?

I tried:

> gsub("[\\]", "/", "c:\temp")
[1] "c:     emp"
> gsub("[\\]", "/", "c:\\temp")
[1] "c:/temp"

Thanks for any help
