R即使在安装软件包后也找不到软件包 [英] R not finding package even after package installation
问题描述
我一直使用很早以前安装的zoo
软件包.今天,我创建了一个新的R脚本,并运行library(zoo)
并收到以下错误:
I have always worked with the zoo
package, that I have installed a long time ago. Today, I created a new R script, and ran library(zoo)
and got the following error:
> library(zoo)
Error in library(zoo) : there is no package called ‘zoo’
奇怪..尽管如此,我还是尝试使用install.packages("zoo")
重新安装软件包,并获得以下信息:
Odd.. Still, I tried reinstalling the package using install.packages("zoo")
, and get the following:
> install.packages("zoo")
Installing package(s) into ‘C:/Users/U122337.BOSTONADVISORS/Documents/R/win-library/2.15’
(as ‘lib’ is unspecified)

The downloaded binary packages are in

当我尝试上传软件包时,再次出现错误,提示zoo
软件包不存在.
When I try uploading the package, I get the error again that the zoo
package doesn't exist.
我不知道发生了什么.我退出了GUI并重新启动它,同样的问题.我一直在使用此程序包,但我不知道为什么现在会发生这种情况.
I have no idea what's happening. I exited the GUI and restarted it, same problem. I have always worked with this package, and I have no idea why this is happening now.
推荐答案
执行.libPaths()
,关闭所有运行的R,检查第一个目录,删除zoo
程序包,重新启动R并再次install
zoo
.当然,您需要拥有足够的权限.
Do .libPaths()
, close every R runing, check in the first directory, remove the zoo
package restart R and install
zoo
again. Of course you need to have sufficient rights.
