As a note, it is extremely hard to help debug code and/or error messages when screenshots are posted. Posting screenshots, instead of actual code/error messages, is likely to decrease your chances of getting the help you are looking for in general. Instead of posting a screenshot, please copy and paste the code and error message and format the pasted code/error messages as shown below.
Put code that is inline (such as a function name, like
filter ) inside of backticks (
mutate ) and chunks of code (including error messages and code copied from the console) can be put between sets of three backticks:
example <- foo %>%
filter(a == 1)
This process can be done automatically by highlighting your code, either inline or in a chunk, and clicking the
</> button on the toolbar of the reply window!
This will help keep our community tidy and help you get the help you are looking for!
