R help - Dec 2014 - Help: The Difference Between Workspace, Script, and History

I apologize that I am very new to R and programming in general. I do not
understand the difference between the script, the workspace, and the
history, and what saving each one means.

I seem to be doing fine writing commands and going through lessons and
examples (I'm using Learn R in a Day) but when I try to save what I wrote
and load it later, it tells me that it is loaded, but none of my code is
one the screen.

Ian,

ls() is your friend. To learn more about ls(), type ?ls

I can answer, but I think you'll get a better one if you tell us the
environment in which you're working -- RStudio, R's GUI, Rterm,... and
the platform (Windows, MAC, _nix).

Very briefly, but perhaps inadequately, the script is what you write
and send to R to execute or perhaps store in its workspace to be run
later (e.g. functions, data); the workspace is the "container" where R
stores its objects -- functions, variables, data, etc. -- that your
script puts there and that R loads by default; and history is simply a
record of the command that you sent to R to run.

I suggest that you have a look at "An Introduction to R" for a better
description of how things work than your current tutorial apparently
gives.

Cheers,
Bert
