I have 2 columns for weight. There are NAs in each column but not for the
same observation. Some observations have values for both. I would want to
prioritize the WT2 values so I would like to do the following:
>From this:
ID WT1 WT2
1 134 NA
2 145 155
1 NA 175
3 NA 187
To this:
ID WT1 WT2 WT
1 NA 175 175
2 145 155 155
3 NA 187 187
Populating the NA values of wt2 with those of wt1 would work as well. Any
suggestions would be greatly appreciated.
