How can I use relative paths in a RStudio project environment?

For example, to access a file, I use the whole path:

# My RStudio project working directory:

getwd()
[1] "C:/Users/MaurizioLocale/OneDrive/Data_Science/10_Capstone_project/
     CP_Natural_Language/MY_FILE.txt"

But it is really long.

I am trying to use paths relative to the working environment. I tried something conceptually similar to:

"~/MY_FILE.txt"

where ~ represents the working environment. Unfortunately, it does not work.

You could change the working directory. Get the address in the beginning getwd(), replace it by your project folder with setwd(). Then, when accessing a file just use read.table("./folder/file.R").
