Thank you!! MyTable has 21 millions rows and 15 columns, and the data is "character", they are words. When I tried the loop my computer crashed in the meaning that it freezed (froze?) and didn't allow me to do anything. The morning after I forced it off and rebooted. :-)
Thank you so much, I'll try your suggestion. -- View this message in context: http://r.789695.n4.nabble.com/loop-for-a-large-database-tp4422052p4422783.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.
