Generally one creates an R script file in an editor and then uses the  
source() function to bring it into R and be executed. Saving data is  
done with the `save` function, ... what else? There is also a history  
mechanism on most OSes, which you have not given us the details. It is  
a separate system that at least on Windows and Macs should be  
operative unless turned off. There are functions that allow you to  
access this file:

?history

You should be able to get prior input from the history file during a  
console session by typing the up-arrow (perhaps repeatedly).

Not sure what you are using as the "Official R Manual". "Introduction  
to R" would be the usual first document.

Try reading the Posting Guide which is linked at the bottom of every  
posting. It has much useful information in it including what is  
requested of persons experiencing difficulties who post to the list.
