未指定的& loadNamespace中的错误 [英] lib unspecified & Error in loadNamespace

问题描述

我可以使用R和RStudio进行所有操作，但是随后在清理计算机目录时移动了文件夹.文件.现在，我收到以下错误消息.

I had everything working with R and RStudio, but then I moved the folders when cleaning up my computer directories & files. Now I'm getting the error message below.

R和RStudio是否应安装在Program Files或Program Files (x86)下?我应该有两个libPaths吗?

Should R and RStudio be installed under Program Files or Program Files (x86)? Should I have two libPaths?

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

推荐答案

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load名称空间错误.通过自动安装软件包，将自动安装所有依赖项并解决此问题.

When you install the package using the RStudio package installer or directly from CRAN, it doesn't install the dependencies ("fracdiff", "Rcpp", "RcppArmadillo" and "colorspace") and hence, R keeps throwing the load namespace error. Installing the package through, automatically installs all the dependencies and solves this problem.

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