I’ve been using this routine for several years. I’m sorry, I don’t remember
where I got it. It works as it should, viz. it blanks the R console. But
it requires package rcom and now that requires rscproxy.

function ()

require(rcom)
wsh <- comCreateObject("Wscript.Shell")
comInvoke(wsh, "SendKeys", "\f")
invisible(wsh)

cls()
Loading required package: rcom

This seems like overkill to me just to blank the R console, especially since
I am trying to diminish the number of necessary packages to support my
home-brew package.
So, is there an easier way to blank the R console in Windows?
Ctrl-L will do it. If you want to put it in a function, I don't think so.
An item that has been on my wish list for a long time is to rewrite the
menu system in the Windows gui so that all items can be invoked from R
code. It's been sitting there in the section entitled "I wish someone
else would do this." It would not be hard, but it would be a lot of
tedious work.
