Question

我正在使用DeployR for Microsoft R Server 2016,8.0.5 for Windows。

我想安装包XLConnect以使用Excel文件：

> install.packages("XLConnect")
package 'XLConnect' successfully unpacked and MD5 sums checked

The downloaded binary packages are in
C:\Windows\Temp\RtmpYnppvI\downloaded_packages

> library("XLConnect")
Console Error there is no package called 'XLConnect'
API Error there is no package called 'XLConnect'

可能有什么不对？谢谢。

如果我们正在使用deployR，则会有一个名为deployrUtils的软件包已经具有deployrPackage函数来加载和安装软件包（如果不存在）

library(deployrUtils)
deployrPackage("XLConnect")

以下是deployrPackage

的代码段

deployrPackage <- function(pkgs, lib, repos = getOption("repos"), ...) {
  #
  # this function checks to see if the declared pkgs are installed. If not, 
  # pkgs are installed. In all cases the packages are loaded
  #
  if (!suppressWarnings(require(pkgs, character.only = TRUE))) {
    install.packages(pkgs, lib, repos = repos, ...)
    if(!suppressWarnings(require(pkgs, character.only = TRUE))) {
      stop("Package not found")
    }
  }

  suppressWarnings(require(pkgs, character.only = TRUE))
}
