Hi
I have two dataframes
names(DF1) = c("id", "val1", "val2");
names(DF2) = c("id2");
Ids in DF2 are a complete subset of those in DF1
How can I extract entries from DF1 where id NOT IN
DF2.
I tried setdiff(DF1, DF2); setdiff(DF1$id, DF2$id),
etc.
Although the latter eliminates the ids as required, I
dont know how to extract val1 and val2 for the
resultant set.
Thanks
Lalitha
