E Getting help

We all get stuck sometimes and need some help. Below are some advises on how to help yourself and ask for help:

If you have a question related to the theory of RL:

• Ask it during the lecture or in the breaks
• Ask it at our course forum and we (the teacher and other students) will try to answer your question asap.

If you have a question related to R:

• First try to understand the error message and solve the problem. You may try to debug your code by inserting browser() in your R code. Further details about debugging can be seen here.
  
• Google is your friend. This is always the next step. Try searches like “r dplyr filter”, “r tidyverse”, “r subset vector”, etc.
• Do you need help for a specific function in R then try ?[function-name] such as ?geom_line, ?mutate, etc. Mostly, focus on the last section with examples. Moreover, some packages may have written vignettes try browseVignettes(package = "package_name") to check.
• Have a look at Help > Cheatsheets in RStudio.
• If you can’t find an answer then it is time to ask on-line. I recommend asking a question at stackoverflow. To make your question effective, the idea is to make things as easy as possible for someone to answer. This stack overflow thread How to make a great R reproducible example? give you some good hints. The process of providing a good minimal reproducible example (reprex) often causes you to answer your own question! See also Stack Exchange’s ‘How to ask’ and How to make a reprex at tidyverse.
• Ask it at our course forum and we (the teacher and other students) will try to answer your question asap.
