[R] How to show help in the same mode as where the commands is input?

[Peng Yu]

Hi,

In R command line, when I type "help(something)", it will always show
the help in the different mode such that I don't see command lines
anymore but just the help document. If I quit from the help mode, I
will only see the command lines by not the help document.

I would like the help document and command lines be show in the same
mode. I'm wondering how to do so.

Regards,
Peng
