R即使在安装包后也找不到包 [英] R not finding package even after package installation
问题描述
我一直使用 zoo
包,我很久以前就安装了这个包.今天,我创建了一个新的 R 脚本,运行 library(zoo)
并得到以下错误:
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.. 不过,我尝试使用 install.packages("zoo")
重新安装软件包,并得到以下结果:
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)

当我尝试上传包时,我再次收到 zoo
包不存在的错误.
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 GUI 并重新启动它,同样的问题.我一直在使用这个包,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
做.libPaths()
,关闭每一个R运行,check in第一个目录,去掉zoo
> 包重新启动 R 和 install
zoo
再次.当然你需要有足够的权限.
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.
