[R] get command history?

[Eric Evans]

Hello,

We are using R 1.4.1 on Solaris 8.  The director of our lab says that it 
should be possible, when using R interactively, to repeat your previous 
command by pressing the up-arrow key (similar to the command history 
feature in the tc shell).  I have not been able to find any mention of this 
command history feature in any of the R documentation, but the lab director 
is adamant that this is a feature of R, because she has seen it work this 
way at another lab.

Does anyone know how to configure R so as to enable the automatic retrieval 
of a previous command by using the up-arrow key?

Thanks very much,
Eric Evans,
Cornell Phonetics Lab
