Fix an outstanding issue in an R package
Most R packages have a corresponding development repository, for example on github. Popular R packages (with many users) may have many open issues, and some are labeled in order to help developers find which issues they can work on.
For example the data.table package uses the "beginner-task" label, and there are a few open issues: https://github.com/Rdatatable/data.table/issues?q=is%3Aopen+is%3Aissue+label%3Abeginner-task
More generally, you could search all of github for R language repository issues that have the word "beginner" somewhere in the label: https://github.com/search?p=2&q=is%3Aopen+is%3Aissue+label%3Abeginner+language%3AR+state%3Aopen&type=Issues
For this task you should fix one such outstanding issue. The task will be considered complete when the issue is closed (by the corresponding package maintainer).
