Split a string vector at whitespace

Question

I have the following vector:

tmp3 <- c(\"1500 2\", \"1500 1\", \"1510 2\", \"1510 1\", \"1520 2\", \"1520 1\", \"1530 2\", 
\"1530 1\", \"1540 2\", \"1540         


        

Answer 1

This should do it:

library(plyr)
ldply(strsplit(tmp3, split = " "))[[2]]

If you need a numeric vector, use

as.numeric(ldply(strsplit(tmp3, split = " "))[[2]])
