What about changing your data frame to matrix and use table set.seed(111) x<-sample(letters, 200, replace=T) y<-letters[3:6] dim(x)<-c(20,10) dd<-data.frame(x) tt<-table(as.matrix(dd)) tt[names(tt) %in% y] c d e f 13 5 8 3 Regards Petr > > > > Thanks!! > > Marianna > > > -- > View this message in context: http://r.789695.n4.nabble.com/loop-for-a- > large-database-tp4422052p4422776.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. ______________________________________________ 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.
