无法安装和加载软件包。

Question

我最近在我的电脑上下载了R和Rstudio。

当我尝试安装ncdf（或任何包）时，我收到以下信息：

> install.packages("ncdf")
Installing package into ‘C:/Users/Talos/Documents/R/win-library/3.1’
(as ‘lib’ is unspecified)
trying URL 'http://cran.rstudio.com/bin/windows/contrib/3.1/ncdf_1.6.7.zip'
Content type 'application/zip' length 358300 bytes (349 Kb)
opened URL
downloaded 349 Kb

package ‘ncdf’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
    C:\Users\Talos\AppData\Local\Temp\RtmpKuMfwR\downloaded_packages

> load("ncdf")
Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection
In addition: Warning message:
In readChar(con, 5L, useBytes = TRUE) :
  cannot open compressed file 'ncdf', probable reason 'No such file or directory'

我尝试进入文件夹并手动解压文件，但好像没有任何改变。

有什么解决方法可以让我安装、加载和使用包？

您需要使用 library 而不是 load。请阅读帮助文件 ? library 和 ? load 以获取更多信息。
