lib未指定&loadNamespace中的错误

Question

我把所有东西都用在了R和RStudio上,但是在清理我的计算机目录和文件时我移动了文件夹.现在我收到以下错误消息.

R和RStudio应该安装在Program Files或Program Files (x86)？我应该有两个libPaths吗？

install.packages("C:/Users/kevin/Downloads/fpp_0.5.zip", repos = NULL)
## Warning in install.packages :
##  package ‘C:/Users/kevin/Downloads/fpp_0.5.zip’
## is not available (for R version 3.0.0)
## Installing package into ‘C:/Users/kevin/Documents/R/win-library/3.0’
## (as ‘lib’ is unspecified)
## package ‘fpp’ successfully unpacked and MD5 sums checked
library("fpp", lib.loc="C:/Users/kevin/Documents/R/win-library/3.0")
Loading required package: forecast
## Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
##   there is no package called ‘colorspace’
## Error: package ‘forecast’ could not be loaded

Answer 1

当您使用RStudio软件包安装程序或直接从CRAN安装软件包时,它不会安装依赖项("fracdiff","Rcpp","RcppArmadillo"和"colorspace"),因此R会不断抛出加载命名空间错误.通过安装包,自动安装所有依赖项并解决此问题.

install.packages("forecast",
                 repos = c("http://rstudio.org/_packages",
                           "http://cran.rstudio.com"))

我最后一次遇到一个非常类似的问题时,我使用了这个代码,我 install.packages("package's name", repos=c("http://rstudio.org/_packages", "http://cran.rstudio.com")) 只是把你的包的名字放在引号中.希望这可以帮助.

用这个:

install.packages("colorspace", dependencies = TRUE)
