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"...
