Dear List:
I have searched the archives and my R books and cannot find a method to
transform a continuous variable into a binary variable. For example, I
have test score data along a continuous scale. I want to create a new
variable in my dataset that is 1=above a cutpoint (or passed the test)
and 0=otherwise.
My instinct tells me that this will require a combination of the
transform command along with a conditional selection. Any help is much
appreciated.
Thanks,
Harold
