Source function in R, error cannot find file - do I have to change working directory?

This may be a duplicate, but I couldn't find a solution when I searched online and it's an issue that has been bugging me for some time. I am given a zip file with 2 .R files, I download the zip and move the .R files into a directory on my computer, let's say "/Users/Home/StatisticsStuff/LearningR/".

My two files are Stats1.R and Stats2.R, and the first line of code in Stats1.R is:

source(Stats2.R)

and I get the following error message:

> source("Stats2.R")
Error in file(filename, "r", encoding = encoding) : cannot open the connection
In addition: Warning message:
In file(filename, "r", encoding = encoding) : cannot open file 'Stats2.R': No such file or directory

when i run getwd(), to see which working directory I'm in, I get:

getwd()
"/Users/Home"

It seems like it would be a pain to have to change working directories in order to source files? Is there something I'm doing wrong here with regards to what I'm expecting from the source() function? Do I have to put a line in my code above everything else using setwd("whatever the correct wd is").

Any thoughts appreciated!

I added this before sourcing, it worked for me :

setwd(dirname(getwd()))

first write this command list.files() then you can know which location of your R is pointing or see the below image that R-Pointing to then write the source command with correct path. it will be executed.

follow these steps to see the R pointing path.

  1. Go to properties of your R software which is installed as below

  2. Find the Start in path: which is the path R pointing to so in source command use that path
