Hi all, I have the following issue:
head(A): C6 5 6.095243 6 12.622674 7 6.418493 8 11.726602 9 9.282112 25 9.625917 head(B): V1 2 30437 5 1102503 6 1102539 7 1103257 8 1103295 9 1104434 25 1100494 I would like to extract elements from B such that their left-most numbers will match those of A (5, 6, 7, 8, 9, 25). However, I am not sure how to do this, since these numbers don't correspond to the indices of these arrays. For instance, Column 0 of B is 30437....1100494. Basically, I am not sure how to extract those numbers that show up to the left. Any help would be much appreciated! And sorry if my lack of programming jargon is confusing.
