[R] Re: reducing learning curves?

Hi all,

Are there any R addon/pluggins with the following feature:

(1) command history? even stores the command history many days ago? Like Matlab does?

(2) online help? for example, as I see it, the Rcmdr is a good companian for a newbie like me who just touched R for 1.5 days. I can use Rcmdr to guide me to learn the commands to use for data analysis. However, Rcmdr does not have online help reference for R commands. For example, I saw the command "abline" and I want to know how to use it, I have to copy/type it in R-console, and do "?abline" things, so that I can obtain help. But this is troublesome, does any editor offer online-help for commands, so I just need to hover my mouse on "abline" and then press F1 key then a help window will open automatically?

Thanks a lot!
