我有一个很长的R脚本，其中包含许多if语句和异常情况.正如我一直在走的，如果我一直在导入和测试库，并且还没有对它们做过很好的记录.问题是，如果我从全新安装运行此脚本，则不确定脚本将运行哪些语句，以及需要哪些库.

I have a very long R script with many if statements and exception cases. As i've been going, if been importing and testing libraries as I've gone and haven't really documented them very well. The problem is that if I run this from a clean installation, i'm not sure which statements the script will run, and so which libraries will be needed.

我的问题是:是否有R函数可以测试脚本中正在使用哪些库?

My question is: Is there any R function to test which libraries are being used in a script?

我还没有使用所有已安装的库，所以print(sessionInfo())不会有用，但是我只想使用install.packages函数启动脚本

I have not used all of the libraries that have been installed so print(sessionInfo()) won't be useful but and I just want to start the script with an install.packages function

推荐答案

我发现NCmisc(install.packages("NCmisc"))的list.functions.in.file()函数对此很有帮助:

I found the list.functions.in.file() function from NCmisc (install.packages("NCmisc")) quite helpful for this:

list.functions.in.file(filename, alphabetic = TRUE)
