Hi,
Try:
dat<- data.frame(id=1:3,abcmor=2:4,relmor=c(5,4,3), neomor=c(6,3,1), Column5=c(4,8,1) )
colnames(dat)[grep("mor",colnames(dat))] <- gsub("mor$","",colnames(dat)[grep("mor",colnames(dat))])
dat
A.K.
I have several columns which all end with "mor". How can I remove the suffix mor for all columns? id abcmor relmor neomor
1 2 5 6
2 3 4 3
3 4 3 1
