How can I resolve the "could not find function vapply" error in R?

Question

I installed the stringr package on my Ubuntu 10.04 machine under R 2.10.1. When I try to use the str_extract() function R stops and gives the following error message:

Error in recyclable(string, pattern, replacement) : could not find function "vapply"

How can I solve this problem? Is there any specific package that contains this vapply function?

Answer 1

vapply is in the base package, so something may be wrong with your installation.

Answer 2

Hi zolizoli, I am getting the same error on same OS and version of R. Reinstalling didn't solve it. Did you reinstall to R version 2.10.1 again?

Answer 3

I'm using Ubuntu and I think the problem is that it's using an older version of R in the repos. I uninstalled R from my machine, then I used this http://www.keittlab.org/node/158 to set up the repos for R. So far this works for me very well.
