Mysterious R ggplot error - Error in list2env(members, envir = e)

Question

I'm encountering an unexpected error while using a simple ggplot command, and I have exhausted all my web-searches to find a similar issue.

qplot(hp,mpg,data=mtcars)

Error in list2env(members, envir = e) : 
  names(x) must be a character vector of the same length as x

The same applies when using ggplot...

ggplot(mtcars, aes(hp,mpg)) + geom_point()
Error in list2env(members, envir = e) : 
  names(x) must be a character vector of the same length as x

I've never had this issue in the past although I am using ggplot after a while.

I'm running R 3.1.1 , any help would be much appreciated!

Answer 1

It works when I updated R to 3.2.3

That required a few administrative requests (work machine) but it's all sorted now.
