This question already has an answer here:
I have a dataset called old_images
One of the columns in this dataset is called difference
, which can take values between 1
and 1115
.
I also have another column called Quarter
, which I want to have values of 1
, 2
, 3
, or 4
depending on what Quarter the difference
value of that row is.
So the rules would be as follows:
If old_images$difference
is between 1
and 279
, then old_images$Quarter
= 1
ELSE
If old_images$difference
is between 280
and 558
, then old_images$Quarter
= 2
ELSE
If old_images$difference
is between 559
and 837
, then old_images$Quarter
= 3
ELSE
If old_images$difference
is between 838
and 1115
, then old_images$Quarter
= 4
Any help would be hugely appreciated, thank you very much!
