Thanks Sean.

The table itself seems to come out fine in the browser - only the hyperlinks don't work! Everything else appears to be formatted.

xtable converts the table to HTML.  You won't want to use write.table
on that.  Use something like writeLines().  Also, the HTML output by
xtable is only the "table" part; you will need to put appropriate HTML
header, body, etc. around the table in order for it to work in a
browser.
