Subject: help recoding
hi R-listers,
I would like some help recoding a variable. I have a dataframe 'cause'
that translates between a set of codes:
acc nds
- -
1 2
3 4
5 8
... ...
the desired result for dataframe 'p':
a
-
1
5
5
would be:
a b
- -
1 2
5 8
5 9
I have tried:
transform(p, b=cause$nds[cause$acc==p$a])
but for some reason it complains about the difference in length between
the translation and result dataframes.
This prints the desired result, but I am unsure how to collect the
results into a variable.
for (i in p) print cause$nds[cause$acc==i]
Any help greatly appreciated.
Selwyn
