Problematic If-Else statement
Hi guys, My code (next 2 lines below) isn't doing what I'm expecting it to: tmp <- ifelse(uncurated$days_to_tumor_recurrence=="null","norecurrence","recurrence") curated$recurrence_status <- tmp I want the column "recurrence_status" in my output file to have values "recurrence" (if the input value had a number in the days_to_tumor_recurrence column for the particular patient) or "norecurrence"...
