readHTMLTable gives me the following errors. Could somebody let me
know how to suppress them?

Just this morning, I made suppressing these parser messages
the default behavior for htmlParse() and that will apply
to readHTMLTable() also.

Until I release that (along with another potentially
non-backward compatible change regarding character encoding),
you can use

 readHTMLTable(htmlParse("index.html", error = function(...){}))

i.e. parse the document yourself and hand it to readHTMLTable().
