[R] Problem with gridExtra

Dear All,
Please consider the snippet at the end of the email, largely based on
what you find here

http://bit.ly/1ND6MGa

When I run it, I get this error

Error in arrangeGrob(p, sub = textGrob("Footnote", x = 0, hjust =
-0.1,  :
  could not find function "textGrob"

However, the code runs on another machine I own. I suppose something
must have changed in the gridExtra library but right now I am banging
my head against the wall.

This is my sessionInfo()
