Hi all, I have a simple question: I have a character vector like this
[1] "10_1" "1_1" "11_1" "2_1" "3_1" "4_1" "5_1" "6_1" "7_1" "8_1" [11] "9_1" "1_3" "2_3" "3_3" "4_3" "1_4" "2_4" "3_4" "4_4" "5_4" [21] "6_4" "7_4" "1_5" "2_5" "10_6" "11_6" "12_6" "1_6" "2_6" "3_6" [31] "4_6" "5_6" "6_6" "7_6" "8_6" "9_6" "1_7" "1_8" "2_8" "3_8" [41] "10_9" "1_9" "2_9" "3_9" "4_9" "5_9" "6_9" "7_9" "8_9" "9_9" [43] "1_10" "2_10" and I'd like to have a vector with only the value after the under scor, like this: [1] "1" "1" "1" "1" "1" "1" "1" "1" "1" "1" [11] "1" "3" "3" "3" "3" "4" "4" "4" "4" "4" [21] "4" "4" "5" "5" "6" "6" "6" "6" "6" "6" [31] "6" "6" "6" "6" "6" "6" "7" "8" "8" "8" [41] "9" "9" "9" "9" "9" "9" "9" "9" "9" "9" [43] "10" "10" Is there a simple function to do this? Thank you for your help All the best Leonardo ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
