Hello, ????????!
mytest<-function(x,f){
sum(x*f)/sum(f)
}
cat(mytest,file="c:/mytest.R")
Error in cat(list(...), file, sep, fill, labels, append) :
argument 1 (type 'closure') cannot be handled by 'cat'
how can i write the mytest function into a file c:/mytest.R with cat function?
Maybe by replacing cat(), e.g., by the use of sink(): sink( "c:/mytest.R") mytest sink() You may want to look at ?dput and ?dget. However, I doubt that that produces what you really want because only the body of your function mytest() will be stored in the file, but not the assignment that created it. Maybe you should store your R-code, i.e., the assignment in a text file (e.g., using R's editor) to -- later again -- use source() to read that file in and have it executed? See ?source.

If you need to use cat() (why?) try using deparse() or format() on the function
cat("mytest <- ", deparse(mytest), sep="\n", file=file)
but dump() is easier
dump("mytest",file=file)
