Question

enter image description here

library(caret)
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
there is no package called ‘SparseM’
Error: package or namespace load failed for ‘caret’

我已经尝试了

install.packages("SparseM", dependencies = TRUE)
install.packages("caret", dependencies = TRUE)

但仍然有同样的错误。

使用以下输出安装了这两个软件包时没有错误。

> install.packages("SparseM", dependencies = TRUE)

  There is a binary version available but the source version
  is later:
        binary source needs_compilation
SparseM   1.74   1.76              TRUE

Do you want to install from sources the package which needs compilation?
y/n: y

也安装了Caret包，没有错误。

这里的问题是没有安装SparseM，因为由于缺少gfortran而导致源代码编译失败。一种解决方案：在提示时不要从源安装。

尝试安装插入包时loadNameSpaces出错
