Googling
Typically when you are “stuck”, it is a good strategy to use Google to find notes from other people who have worked through your same problem. If you phrase your search terms carefully, relevant results from Question/Answer sites such as StackExchange will appear and you can often get insights on approach, code examples, and be pointed toward other resources. If you decide to post a question yourself, use these guidelines.
Resources within RStudio
Within RStudio you can read the documentation of any package or function that you have installed.
In the lower-right pane of RStudio (with tabs: Files, Plots, Packages, Help, and Viewer), click the Help tab and use the search bar to look for names of packages or functions. You can also search Packages and click on the name of a package to see its Help documentation.
For packages, the Help page will contain:
- A description file
- General description and link to offline Help pages for each function contained within the package
For functions, the Help page will contain:
- A general description
- Usage, showing the required and optional arguments and their expected order within the function.
- Detailed requirements of each argument
- Examples of use
