Generating new locales for R to access

gen_locale_for_R.sh

# When working with R files created using locales that are not installed, this is how you generate new ones. 
# Works on Ubuntu 20.04.4 LTS

# prints out locales that are already created and accessible.
locale -a 

# generate a new one, for example French
locale-gen fr

# Update the locales so that R can access them
locale-update

# In R, use Sys.getlocale() to get all the locales that are available. 
# Sys.setlocale("LC_ALL","fr_FR.utf8") using the locale info will set it for you.
