StackOverflow
- I encourage you to create an account so you can post questions. But even without an account you can search for and find answers to your questions and error messages.
Google
- You can often cut and paste error messages in Google to find answers - most likely will redirect you to Stack Overflow.
Package vignettes for packages on CRAN
- Here is one vignette for dplyr
- These will often help you get started.
Github package issues
- Many packages will host their code on Github which includes an “issues” tab. This can be a good place to see what other problems people may be having with a given package.
- dplyr issues on Github
CRAN package site
- dplyr on CRAN - spend time looking at:
  - the README for the package or
  - bug reports or
  - NEWS which will detail the changes for each version updates
R Bloggers
- This is a really good website which curates thousands of people who are R developers, users and programmers who post articles about R.
STHDA Website for “Statistical tools for high-throughput data analysis”
- This website will often come up when “Googling” for answers. It has a lot of ads but often has very helpful examples.
