Automatically finding the path of current R project in R Studio
r, rstudio
Solution
It sounds like the rprojroot package will provide what you're looking for -- in particular, the `find_rstudio_root_file()` function should provide what you need.
Problem
Say I have an R project opened at the following directory `/home/user/workarea/project1`. Now I have a nested directory structure underneath and I am writing a function that is supposed to perform logging from anywhere inside this project and I want this function to write into files that are located at the directory `/home/user/workarea/project1/log`. I plan to pass the file path as an argument to this function. Now I know that this file will always be located under the /log directory in the project's main directory - but how do I automatically find out which is my project directory, so that I don't always specify relative paths with `..`. I wouldn't want to hard-code my local path `/home/user/workare/project1`, but be able to detect this wherever I clone my project.
