无法使用ggplot2

Question

安装和使用ggplot2时出错

install.packages("ggplot2")

library(ggplot2)

错误:loadNamespace中的“Rcpp”包或命名空间加载失败(j <- i[1L]，c(lib.loc，.libPaths()，versionCheck =vI[j]))：除了警告消息:软件包‘ggplot2’是在R版本3.4.3下生成的，没有一个包称为‘Rcpp’。

Answer 1

请执行以下步骤

1) install.packages("Rcpp")

Installing package into ‘C:/Users/username/Documents/R/win-library/3.4’
(as ‘lib’ is unspecified)

Content type 'application/zip' length 4358875 bytes (4.2 MB)

package ‘Rcpp’ successfully unpacked and MD5 sums checked
Warning in install.packages :
  unable to move temporary installation ‘C:\Users\username\Documents\R\win-library\3.4\file173429377309\Rcpp’ to ‘C:\Users\username\Documents\R\win-library\3.4\Rcpp’

The downloaded binary packages are in
    C:\Users\username\AppData\Local\Temp\RtmpQJ4SRf\downloaded_packages

C:\Users\username\AppData\Local\Temp\RtmpQJ4SRf\downloaded_packages 2) Goto

3)将Rcpp_0.12.14.zip解压缩到C：\User\username\Documents\R\win-Rcpp_0.12.14.zip\3.4
