Converge style functional using R

0 votes

Here's my list of r binary files:

filenames<-c(f1,f2,f3 .... fn)

I use a loadBinFile(fname) function which reads my files and then returns a data frame. Is there a way to write a coverge program that goes through the files list and simultaneously builds an entire big data frame?

Can this be done in R?

This should do it:

do.call("rbind", lapply(filenames, loadFile))
