[R] Reading CSV file every time when R starts

However, be careful, because .Rprofile runs before any saved .RData file
is loaded. If the object you created in .Rprofile is later saved when you
quit R, then the next time you start R, the saved version will replace the
version created in .Rprofile. (Unless you start R using R --no-restore)
This means that if you create the object in .Rprofile, and then later
change it, then later save it when you quit R, the next time you start R
you will have the modified version, not the original version.

See ?Startup for this information (?Startup also answers your original
