Letter to numerb: Create a new 'if' variable to change 'Y' and 'N' to 1 and 0

3 次查看(过去 30 天)
I would like to create a new variable and change those 'N's and 'Y's to 0 (N) and 1 (Y).
Does someone know an easy way to solve the problem?
Best regards
Max

What does that mean, pray tell? What is "it" and what are you trying to accomplish?
Above is three slightly different approaches to converting a string variable Y/N to a logical one...
BTW, there's no data in the attached spreadsheet that shows anything that appears to be at all related to the question asked...
