r - DeployR：如何安装 R 包

Question

我将 DeployR 用于 Microsoft R Server 2016，8.0.5 用于 Windows。

我想安装包 XLConnect 来处理 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'

有什么问题？谢谢你。

如果我们正在使用deployR，则有一个名为的包deployrUtils，它已经具有deployrPackage加载和安装包的功能（如果不存在）

library(deployrUtils)
deployrPackage("XLConnect")

下面是代码片段deployrPackage

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))
}
