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

Another option is scan(). To get the second value, we can use a logical subset.

scan(text = tmp3)[c(FALSE, TRUE)]
#  [1] 2 1 2 1 2 1 2 1 2 1
