我对 R 很陌生，但我无法继续，因为我一直在加载包时遇到同样的问题。我安装包然后去加载它，这就是发生的事情：
> chooseCRANmirror()
> install.packages("psych")
trying URL 'http://cran.mtu.edu/bin/windows/contrib/3.0/psych_1.3.10.12.zip'
Content type 'application/zip' length 2684126 bytes (2.6 Mb)

package ‘psych’ successfully unpacked and MD5 sums checked
Warning: unable to move temporary installation ‘C:\Program Files\R\R-3.0.1\library\filedc04ebd378e\psych’ to ‘C:\Program Files\R\R-3.0.1\library\psych’
The downloaded binary packages are in
C:\Documents and Settings\rbrown\Local Settings\Temp\RtmpcVNWuA\downloaded_packages
> library("psych")
Error in library("psych") : there is no package called ‘psych’
请帮忙。
