Count number of rows in a matrix with a character pattern
Hi, I have a large data set that I input as a matrix, where I have 1:x rows with names AX, then x+1: y rows named AY, etc. The idea is that I have to count how many rows exactly I have with name AX and how many I have with name AY (or find which row numbers have names AX). Is there any way in R to count a number of rows with a name matching a required pattern? Thanks in advance, Katie --
