Hi, You could also use ?colwise() from library(plyr) set.seed(50) dat1<-data.frame(Col1=sample(1:20,10,replace=TRUE),Col2=sample(LETTERS[1:10],10,replace=TRUE),Col3=sample(LETTERS[11:20],10,replace=TRUE),Col4=sample(40:60,10,replace=TRUE)) dat1[unlist(colwise(is.factor)(dat1))] # Col2 Col3 #1 D Q #2 C L #3 G R #4 A S #5 C N #6 G Q #7 I P #8 D M #9 A N #10 B N dat1[unlist(colwise(is.numeric)(dat1))] A.K.
