a question about replacing a column that is factor
...mn that is a factor. However this
column is replaced by <NA>
, which is not what I want. I know this is because the new value is not in
the levels of that column, but
I don't know how to fix it.
Can someone help me to figure this out?
The following is what I did
thanks
