How can I make R read my environmental variables?

Question

I am running R on EC2 spot instances and I need R to terminate the instance and cancel the spot request once the script has run.

Answer 1

I'm pretty new to R but my approach was this: I had project-level environment variables stored in a .env file. To make it accessible in R, I used

> readRenviron(".env")

Then to access a specific variable

> Sys.getenv("RDS_UID")

And it worked perfectly.
