Hi everyone, I read your messages and I tried some things out. The Data2 is filled with NA. So what I did was:
NameFile.csv$Data2[is.na(NameFile.csv$Data2)] = log2Values And now it worked. :) Seems like I needed to replace it, and not only write it. Thanks. -- View this message in context: http://r.789695.n4.nabble.com/How-insert-data-to-a-column-in-existing-csv-file-tp4551327p4552463.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
