Hi,

That is an error message from 'latex' indicating that you may have too many float tables without sufficient separation (eg. new pages, text in between, etc.) and/or conflicts in table placement.

You might have a look at the relevant TeX FAQ here:

  http://www.tex.ac.uk/cgi-bin/texfaq2html?label=tmupfl

Also, while I don't use xtable(), I do believe that you have to call it using the print method directly to specify non-default arguments:

  print(xtable(q5.tab, align = "l|c"), caption.placement = "top", table.placement = 'H')

See the help pages for ?xtable and ?print.table, including the last examples in the former.

HTH,
