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

Question

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.

I know this question is outdated, but I was searching for a solution for that as well and Google lists this at the very top:

this.dir <- dirname(parent.frame(2)$ofile)
setwd(this.dir)

put that somewhere into the file (best would be the beginning, though), so that the wd is changed according to that file.

According to the comments, this might not necessarily work on every platform (Windows seems to work, Linux/Mac for some). Keep in mind that this solution is for 'sourcing' the files, not necessarily for running chunks in that file.

dirname(rstudioapi::getActiveDocumentContext()$path)

works for me but if you don't want to use rstudioapi and you are not in a proyect, you can use the symbol ~ in your path. The symbol ~ refers to the default RStudio working directory (at least on Windows).

If your RStudio working directory is "D:/Documents", setwd("~/proyect1") is the same as setwd("D:/Documents/proyect1").

Once you set that, you can navigate to a subdirectory: read.csv("DATA/mydata.csv"). Is the same as read.csv("D:/Documents/proyect1/DATA/mydata.csv").

If you want to navigate to a parent folder, you can use "../". For example: read.csv("../olddata/DATA/mydata.csv") which is the same as read.csv("D:/Documents/oldata/DATA/mydata.csv")

This is the best way for me to code scripts, no matter what computer you are using.

For rstudio, you can automatically set your working directory to the script directory using rstudioapi like that:

library(rstudioapi)

# Getting the path of your current open file
current_path = rstudioapi::getActiveDocumentContext()$path 
setwd(dirname(current_path ))
print( getwd() )

This works when Running or Sourceing your file.

You need to install the package rstudioapi first. Notice I print the path to be 100% sure I'm at the right place, but this is optional.

This answer can help:

script.dir <- dirname(sys.frame(1)$ofile)

Note: script must be sourced in order to return correct path

I found it in: https://support.rstudio.com/hc/communities/public/questions/200895567-can-user-obtain-the-path-of-current-Project-s-directory-

The BumbleBee´s answer (with parent.frame instead sys.frame) didn´t work to me, I always get an error.
