Birgit Lemcke: > I have a dataframe and two of my variables are in the wrong position > and I would like to swap those variables. To swap column 1 and 2, try d[c(1,2)]=d[c(2,1)] Note that this is different from d[,c(1,2)]=d[,c(2,1)] which will swap the data, but not the column names. -- Karl Ove Hufthammer
