How to set working directory to source file location in R

Question

I am working on various codes put in a folder. I want to open the .r file and source it such that I do not have to change the working directory in Rstudio as shown below:

Is there any command to specify my working directory automatically in R.

Answer 1

You can try out this solution:

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

Put the above code somewhere in the file so that the working directory is changed according to that file.

Answer 2

Hi, 

I'm not sure about the command but you can try this way to see your files, directory as well as set it as your working directory.

You have an option on the right bottom of the screen to set the working directory by going to that file location or directory.

Click on files ->Then go to the file location or directory.

Then go to more and click on set as a working directory.

Hope it helps!
