以下在RStudio控制台中工作正常：
source("https://gist.githubusercontent.com/ajit555/f7a3d2ccfd5ab305cd3f/raw/a931585306ccb977ae13b8e2b20e78a4a71fdd2c/HelloGist.R")
但是当在RGui控制台中运行时，会出现以下错误：
source("https://gist.githubusercontent.com/ajit555/f7a3d2ccfd5ab305cd3f/raw/a931585306ccb977ae13b8e2b20e78a4a71fdd2c/HelloGist.R")
Error in file(filename, "r", encoding = encoding) :
cannot open the connection
In addition: Warning message:
In file(filename, "r", encoding = encoding) : unsupported URL scheme
在RGui控制台中正常运行需要做什么？
