[R] Create directory and copy files in R

[Tammy Ma]

HI, All R users,

My problem is:

> fn
[1] "C:/Documents and 
Settings/lma/Desktop/FamilyAEntrepreneurs/Entrepreneurs/Juha/book_log-20041210T095019.txt"
> dpath
[1] "C:/Documents and Settings/lma/My Documents/Juha/book"


I want to make  a function "cyfun" to copy all files in "dir" to "deskdir" but 
I always got the following problem:

Error in file.exists(to) : invalid 'file' argument.
Whats the problem??




cyfun<-function(fn,dpath){
dir<-dirname(fn)
fn<-basename(fn)

deskdir<-dir.create(dpath)
file.copy(fn, deskfile)

}

Thanks!

Tammy
