[R] R console history v/s unix history

[steven cha]

Hi

i'm new to R and find that the "history" functionality works a little
different than in unix. A very convenient feature of history in unix
is the ability to recall a comand by typing in !x where x is a letter
and the latest matching command in the history that starts with the letter
is (re)called. This is useful for instance, when calling a "source" command
by !s rather than having to scroll back using the arrow key. Does this
functionality exist in R and if not any suggestions on how to replicate
it?

Also:
- is there a way to open a second *console* window within RGui (running
within the microsoft windows MDI)?
- how do i check to see what the installed version of a package is?

Thanks in advance.

steve
