When working interactively, you can find a previous command that starts with a certain letter by typing such a letter and then pressing the cursor up key. In R I've seen that, despite the letter you type, when pressing the cursor up key, it goes to the immediately previous command.

This depends on what front end you are using.  In the Windows Rgui.exe,
you get what you saw.  In front-ends using readline, you can do it by
hitting Ctrl-R first.  (The Windows command-line interface, Rterm.exe,
uses this, as do many others.)  If you're using some other front-end,
you'll need to read its documentation.
