Re: [R] How to match some patterns in a matrix

1. Strictly speaking, y is a one-column matrix if it has a non-null dim attribute (it also is a vector). 2. ?match or ?"%in%" tells you what to do. x2[x2[["name"]] %in% y,] is what you want. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of ss Sen
