vector
The first column has 331 rows, the number of factors in the second
column is
20 repeated in order to have 331 rows too. What I need is to reapeat in
the
third column each of the 20 results derived from tapply(firstcolumn,secondcolumn,mean) as many times as each factor
appears
in the second column. So I'll have 331 values in the third column as
well.
I hope it's clear enough what I need to do. -- View this message in context:
