如何调用其他人编写的R函数？

Question

我从R开始，在互联网上遇到了某人写的这个功能。链接是这个

https://gist.githubusercontent.com/fawda123/5086859/raw/17fd6d2adec4dbcf5ce750cbd1f3e0f4be9d8b19/nnet_plot_fun.r

现在，如果我想下载此文件然后调用该方法，我应该在哪里下载并存储此文件？如何调用此方法？

Answer 1

或者，尝试

# install.packages("devtools")
library(devtools)
source_gist(5086859)
plot.nnet

Answer 2

# just run this line your first time to install the package
# install.packages( "downloader" )

# the downloader package makes it easy to pull code from github
library(downloader)
source_url( "https://gist.githubusercontent.com/fawda123/5086859/raw/17fd6d2adec4dbcf5ce750cbd1f3e0f4be9d8b19/nnet_plot_fun.r" , prompt = FALSE )

# there you have it
plot.nnet
