[R] Problem with readHTMLTable

[R. Michael Weylandt]

Odd... it doesn't throw an error for me.

Two things possibly come to mind, but I don't know enough of the XML
internals to know if they're reasonable. First is that something seems
funny about your version number -- mine is simply XML_3.9-4  (no added
"-1"); do you have any idea why yours would be different? Could you
reinstall the package with Prof Ripley's build (I believe the regular
install.packages() route should work after you uninstall with
remove.packages()) and see if that fixes it? It could also possibly be
an encoding/locale issue but that seems less likely.

Hope this gets you going in the right direction,

Michael
