I have a dataset with excess return, R, which consists of 10 000 rows and 1 column.
I want to create a new variable X that takes the value of 1 for each row in R if R>0 for all rows in R. And it takes the value of 0 if R<0.
Probably a simple question, but couldnt find any other answers out there that worked for me.

X = R > 0
