Changing frequency values to 1 and 0
Dear list,
I'm working with a large data set, where I grouped several species in one
group (guild). Then I reshaped my data as shown below. Now, I just want to
have "Rep" only as 1 or 0.
I'm not being able to change the values of rep>=1 to 1... tried many things
and I'm not being successful!
