[R] Reloading old R Environments/Workspaces

[Jeff Newmiller]

An R file is nothing more than a text file with an R extension instead of a TXT extension. Use any text editor you like to rearrange your commands in the order you want and remove false starts (beware of Notepad... it seems to have a tendency to tack on a .txt extension in addition to the .R extension of you are not careful).

If you use an R development tool like ESS or RStudio or Notepad++ with the R extension, you can type all of your commands into the file editing window first and you can use a hot key to copy them to your R console. That way you make a file and test your commands as you write them, all at once.
