You should review the ListInfo material. Most of these questions have nothing to do with the Mac version of R.

You should be trying help.search() or it's shortcut `??`

Not sure what you are considering "interfaces". Pretty much everything is on disk.

They are generally automagically reloaded if you exited in a manner that saved them and restart from the same directory. The state of the previous session is stored in a special .Rdata file which is invisible to Macs and Windoze machines by default. You need to modify your system file manage to see them. Read about .Rdata files and how to use them.

Sadder words were never written, but most of the sadness derives from the failure to efficiently communicate what "it" actually was.

R does recognize space on a Mac. You need to provide actual code. I cannot intuit what errors you are making from this description.

Well you are not reading the documentation for this list (or any of the several R-project list) since you are posting in HTML.
