無法安裝和加載軟件包

Question

我最近將R和Rstudio下載到了我的電腦上。

當我嘗試安裝包ncdf（或任何包裝）我得到以下信息：

> 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' 

我試圖去到該文件夾​​並手動解壓縮文件，這似乎是沒有什麼區別的所有。

這是什麼解決方案，以便我可以安裝，加載和使用包？

你想要library而不是load。請閱讀幫助文件? library和? load瞭解更多信息。
