安装包时 R 出错：闪亮或 java_home 有问题？是因为opensteetmap吗？

Question

不幸的是，我是 R 的新手，但我需要它来打开一个应该是图形用户界面的特定文件。源命令后：

source("D:\R\win-library\3.5\muxViz-master\muxVizGUI.R")

我遇到了这个错误：

"Installing package into ‘D:/R/win-library/3.5’

请帮忙。

Answer 1

muxVizGUI.R的最后一行是runApp(getwd())。它希望您的工作目录与 ui.R 和 server.R 文件所在的目录相同。您应该在获取文件之前更改到该目录：

setwd("D:\R\win-library\3.5\muxViz-master")
source("muxVizGUI.R")

安装包时 R 出错：闪亮或 java_home 有问题？是因为opensteetmap吗？
