Searching for functions in R library

Question

New to the forum. Is there a way to search for functions within a particular library in R?

Lets say I would like a list of all the functions in the "graphics" library. How would do that?

If I want to find the specific documentation on the "plot" command I am having trouble finding the documentation when I used the help.search("plot"). It gives me all these other functions from different libraries. I just want to be able to find and narrow down the searches when I look for a particular function.

Answer 1

For a listing of all the functions within a package, and links to their documentations, do:

help(package = "graphics")

That of course assumes that you have installed the package.

For your other question:

If you already know the name of the function you are looking for, do not use help.search("plot") but help("plot"). As the name suggests, help.search does a search through all the docs and returns every hit, very much like a Google search.

Finally, know that you can use:

• ?plot as a shortcut to help("plot")
• ??plot as a shortcut to help.search("plot").
