[R] Is 'history' recorded in Rscript?

You should be looking for .Rhistory

Some OSes make that task difficult. "savehistory" is not the file name
but rather the name of the function that performs that operation. Try
savehistory(file="text.Rhistory") and see if the history file is
easier to find. Should be in your working directory.

Rscript is a program, not a record of the prior session.
