Hello!
The overall goal I have is taking a large data frame and splitting it into several smaller data frames (preserving column headers) which I can save as txt files to feed into my APACHE ANY23 server for conversion into RDF. This is what I call to split up the original file: out <- split(affymetrix, (seq(nrow(affymetrix))-1) %/% 140) I have a list (out) of length 187 for which each element is a dataframe. I want to iteratively save each data frame as a separate tab file with a naming structure such as: affymetrix1.txt, affymetrix2.txt, ... affymetrix187.txt Before that, I need to modify the headers to remove a prefix "X0. , X1., ... X187." that was introduced during my original splitting. I need to remove all characters before and including the first "." If anyone has a better way of doing this, please let me know. Otherwise, help with how to perform batch editing of the headers and batch saving of the files would be greatly appreciated! Best, Christian T.
