Also possible is
is.na (B) <- B >= A
Hope this helps,

You understand, of course, that all columns in a data frame must be of the
same length; and that "NA" is not the same as NA?
This is pretty basic stuff and suggests you need to spend some time with an
R tutorial or two.
In any case, a construct of the form:
B[B >= A] <- NA
should do.
Cheers,

Dear R users;
I have two columns data frame (column names is A and B). I want to write a
function in order to compare column of B with A and if the values of B are
equal or greater than that of A, replace them with "NA" or delete them and
if the values of B are less than values in A, do nothing.
