Hi, Thanks for the help and the manuals. Will come very handy i am sure.
But regarding the code i don't hink this is what i want....basically i would like to repeat bellow code : w1<-table(lit$W1) w1<-as.data.frame(w1) write.table(w1,file="w1.csv",sep=";",row.names=T, dec=".") w1<- w1[order(w1$Freq, decreasing=TRUE),] w1<-head(w1, 20) 20 times, where W1-20 (capital letters) are the fields in a data.frame called "lit" and w1-20 are the data.frames being created.
