R help - Oct 2009 - Urgent help requested to modify a script

I am hoping someone will tak up this chalenge (I am new to R)

I have inheritied an R script but need to change it. The script currently
includes hardcoded file locations on lines 12,166 and 167. I need to modify
this script to allow the folder to be passed as a command line argument to
Rscript.exe

Can anybody help please?

Regards,

Ian

Hi Ian,
You can do something like this:

pdfoutputfile<-"/home/jim/R/Rplots.pdf"
pdf(pdfoutputfile,...)

and similarly for the other instances. Unfortunately, you can't just 
define a path and pass it as an argument, for functions like "pdf" and
"read.csv" won't stick the path and filename together unless you
write a
wrapper for each function that creates the complete path/filename and 
then passes it to the original function.
