I am sorry not having looked carefully on the documentation. But the
first thing I do is to launch help.start() and be stuck with an
inexistent browser. I have imagined that help.start(browser="opera")
would set the browser to opera, but I am wrong and the browser must be
set by options(browser="opera"), a feature which I am not aware of.
Nevertheless, I find this rather confusing for a new user: if
options(browser="opera") should always be used to set the browser,
then the argument browser="opera" in help.start would never be needed.
