Hi jholtman,
Thanks a ton it just worked. if you dont mind can you explain the code it a
little
sapply(seq(from = 1, by = 2, length = ncol(x) %/% 2), function(a){
+ x[[a]] - x[[a + 1]]
+ })
wat is the purpose of double percent sign and is the sapply the function we
generally use for the Dataframe?
Thanks
Ramya
