Hi all,
I have a data frame that has the columns OFB1, OFB2, OFB3,... OFB10.
How do I select the first 8 columns efficiently without typing each and
every one of them. i.e. I want something like:
a<-data.frame(initial_data$OFB1-10) #i know this is wrong, what would be
the correct syntax?
Thanks,
Sachin
