sample codes for writting a function with unknown number of arguments

Hi,

I need to scan some files, and then do a boxplot graph of them.  I also 
save the output from the boxplot function, so I can process the data later.

For example, I need to scan 2 (it can be x, 0<x) files here.
A<-scan(F1)/100;
B<-scan(F2)/100;

Now let's try graph it. N1 is the label for F1, and so on.
bitmap(file=Name, type="png16m")
STATS<-boxplot(A,B,c(A,B),col="red", main="MyMain", names=c(N1, N2, 
"All"), xlab="Hardware", ylab="milliseconds")
dev.off();

The problem is I don't really know what I will have at runtime.  For 
example, I may have to scan 3 or 4 files at runtime.  Then, I will have to 
pass different arguments to boxplot, like

STATS<-boxplot(A,B,C,c(A,B,C),col="red", main="MyMain", names=c(N1, N2, 
N3, "All"), xlab="Hardware", ylab="milliseconds")


The function should look like:
process<-function(Name, F1, F2...N1,N2...)

How should I write a function that is flexible enough to handle this 
situation?  Thank you in advance.
