[R] character vector as input to function?

[Bill Simpson]

I would like to have a function that inputs a file name, then reads that
data file and does various stuff to it.
Something like:

doit<-function(filename)        
{
x<-scan("~/rstuff/data/"filename)
#for example, if filename is a0.dat, it will scan("~/rstuff/data/a0.dat")  
...
}

Can someone please tell me how to do this?

Thanks for any help!
