R command for setting working directory to source file location in Rstudio

by

To get the location of a script being sourced, you can use utils::getSrcDirectory or utils::getSrcFilename. So changing the working directory to that of the current file can be done with:

setwd(getSrcDirectory()[1])

This does not work in RStudio if you Run the code rather than Sourceing it. For that, you need to use rstudioapi::getActiveDocumentContext.

setwd(dirname(rstudioapi::getActiveDocumentContext()$path))

This second solution requires that you are using RStudio as your IDE, of course.
