Matching rows in a Data set? I'm Stuck!!
Hi, I'm having (yet another) problem with R.
I have a few data sets that have this sort of format
dataset1
ID DATA
1234 value
2345 value
3456 value
dataset2
ID DATA
1111 value
2345 value
3333 value
What i really want to do is write an R script that says "if the ID of
dataset1 and 2 match (2nd row), print out that whole row into a new
dataset3". No idea how to do that though.
