Error when running library(ggplot2)

Question

I just updated to R 2.11.1 and after installing ggplot2, I tried

library(ggplot2)

and got

Loading required package: proto
Loa         


        

Answer 1

I had the same problem and this did the trick.

1. Install the lazyeval package.
2. Then install ggplot2
3. Load the ggplot2 library and everything will hopefully work fine.
