R info and error and warning messages showing in Spanish for some reason... How to change back to English?

Question

I recently made a trip to Spain with my laptop, and ever since then, all R warnings and error messages show in Spanish. I don't recall having changed any settings at all.

This only happens in R, everything else shows properly in English.

I am on macOS Monterey using R version 4.1.2. Language & Region in my System Settings are correctly set to my current location and preferred language (English).

However, R still shows everything in Spanish... My Sys.getlocale() shows the following:

> Sys.getlocale()
[1] "C/UTF-8/C/C/C/C"

See screenshot for the last error message I got trying some new code... when launching R, the main welcome message shows in Spanish too... Thanks!

This question has been answered before in greater detail but in short, you can use Sys.setenv() and set LANG = "en". This is a temporary solution but long-term solutions are in the link above. Hope this helps!
