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.
