r - Use grep to parse column names -


there data frame want delete columns in there string xfl or xst in colname. colname not exclusively xfl can ktel_xfl or ktel_xst. know there has way grep?

here's approach:

# create cloumn index idx <- grep("x(fl|st)", colnames(dat), invert = true) # filter columns dat[idx] 

where dat name of data frame.
