# we will demonstrate this procedure with the crabs data.

demFS = fs.absT(3)
# run it on the entire dataset with features excluding sex

# emulate cross-validation by excluding last 50 records

# emulate cross-validation by excluding first 50 records -- different features retained
demFS(sp~.-sex, crabs[51:200,])
