[R] I want to fill a column in with 0 or 1 depending on another columns input
This is a portion of my data frame
MemberID Specialty Surgery Internal
1 42286978 Surgery NA NA
2 97903248 Internal NA NA
3 2759427 Internal NA NA
4 73570559 Surgery NA NA
There are four columns. In the Specialty column there are two options
Surgery/Internal, These options have there own columns.
I want to fill a column in with 0 or 1 depending on another columns input
I am finding it hard to figure out how to do the following:
MemberID Specialty Surgery Internal
1 42286978 Surgery 1 0
2 97903248 Internal 0 1
3 2759427 Internal 0 1
4 73570559 Surgery 1 0
I would greatly appreciate any help
regards,
Kevin
