Maybe, but you're not giving us much to go on...

If the page really isn't HTML or XML, then readHTMLTable() is not going to help you. So perhaps first see what is in there; either by opening the URL in a browser and using View Source, or by using

con <- url(url) ## you might want to reconsider the naming...
readLines(con)
close(con)
