I just updated to R 2.11.1 and after installing ggplot2, I tried
library(ggplot2)
and got
Loading required package: proto
Loading required package: grid Loading
required package: reshape Loading
required package: plyr Loading
required package: digest Error in
eval(expr, envir, enclos) : could not
find function "proto" In addition:
Warning message: In library(package,
lib.loc = lib.loc, character.only =
TRUE, logical.return = TRUE, :
there is no package called 'proto'
Error : unable to load R code in
package 'ggplot2' Error:
package/namespace load failed for
'ggplot2'
Any help appreciated.
