Edit Question
Title
Body
I would like to choose rows based on the subsets of their names, for example If I have the following data: data <- structure(c(91, 92, 108, 104, 87, 91, 91, 97, 81, 98), .Names = c("fee-", "fi", "fo-", "fum-", "foo-", "foo1234-", "123foo-", "fum-", "fum-", "fum-")) how do I select the rows matching 'foo'? using grep() doesn't work: grep('foo', data) returns: integer(0) what am I doing wrong? or, is there a better way? Thanks!
