r-loadNamespace(i，c(lib.loc，.libPaths())，versionCheck=vI[[i]

Question

基本上我想使用wordcloud函数。我正在通过R控制台工作。但如果有问题的话，我可以使用Rstudio。

当我使用时

 wordcloud(r_stats_text_corpus)
 Error: could not find function "wordcloud"

我也试过

library("wordcloud")
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) : 
  there is no package called ‘Rcpp’
Error: package or namespace load failed for ‘wordcloud’

然后：

install.packages("Rcpp")
Installing package into ‘C:/Users/Abbas/Documents/R/win-library/3.2’
(as ‘lib’ is unspecified)
trying URL 'https://pbil.univ-lyon1.fr/CRAN/bin/windows/contrib/3.2/Rcpp_0.12.3.zip'
Content type 'application/zip' length 3197148 bytes (3.0 MB)
downloaded 3.0 MB
package ‘Rcpp’ successfully unpacked and MD5 sums checked
Warning: unable to move temporary installation ‘C:UsersAbbasDocumentsRwin-library3.2file2388511e56acRcpp’ to ‘C:UsersAbbasDocumentsRwin-library3.2Rcpp’
The downloaded binary packages are in
        C:UsersAbbasAppDataLocalTempRtmpwrnScPdownloaded_packages

当我检查路径C:UsersAbbasDocumentsRwin-library3.2file2388511e56acRcpp时，我只能找到空文件夹。我还是把这个文件夹移到了C:UsersAbbasDocumentsRwin-library3.2Rcpp。即使在这之后，当我尝试加载Rcpp包时，我也会收到错误。

library("Rcpp")
Error in library("Rcpp") : there is no package called ‘Rcpp’

此外，当检查路径C:UsersAbbasAppDataLocalTempRtmpwrnScPdownloaded_packages时，我可以在那里看到zip文件Rcpp_0.12.3。

救命！

编辑：当我通过Rstudio尝试这个时，我在这里错过了什么？

> install.packages(Rcpp)
Error in install.packages : object 'Rcpp' not found
> source('~/.active-rstudio-document', echo=TRUE)

感谢您的帮助。我搞定了！手动将Rcpp zip文件提取到.libPaths() 中提到的路径
