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

install.packages('ggplot2', dep = TRUE) would do the trick... install proto package

Answer 2

Also have had troubles, when installing ggplots2, but here is a curious solution (tested on windows):

• I installed via RStudio. Both from Tools->install packages and by typing install.packages("ggplots2", dep=T). It didn't work because it kept not installing the dependencies.

• I then installed direct by R gui install.packages("ggplots2", dep=T) and everything went well.

Answer 3

Open R shell and type following in it

install.packages('ggplot2', dep = TRUE)

then it will ask you to select the mirror, select closest one and it will install it and solve your problem.

Answer 4

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.
