运行库时出错(ggplot2)

Question

我刚刚更新到R 2.11.1,安装ggp​​lot2之后,我试过了

library(ggplot2)

得到了

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'

任何帮助赞赏.

Answer 1

install.packages('ggplot2', dep = TRUE)会做的诀窍......安装proto包

Answer 2

打开R shell并在其中键入以下内容

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

然后它会要求你选择镜子,选择最近的镜子,它会安装它并解决你的问题.
