Dear all,I had just started to learn R. So my question may sound a bit stupid for you. Is that possible to match and merge two tables in R? I mean I have two tables, in the first I have two columns: RING NUMBER, WEIGHT and CAPTURE
Err, ... for large values of "two"? Or is one of the three a rowname?
DATE, in the second RING NUMBER, SEX and CAPTURE DATE. 1) First I want to see, if to the ring numbers are the same, the capture dates are too? 2) And second if ring numbers are the same, to import the sex from the second table in the first. Is that possible?
Yes. It's a job for merge()
