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

3 views (last 30 days)
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

ans =
3×1 categorical array

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...
