[1] "as.integer(8)"

Why the as.integer() representation? I later pass the result into this 
write.html.table(), and what I get is rows of as.integer()... when all I 
want is the integer itself.

as.integer(31) 	as.integer(21) 	as.integer(34) 	as.integer(86)
as.integer(7) 	as.integer(6) 	as.integer(15) 	as.integer(28)


write.html.table <- function(t, file= "", capt= "The Default Title",
                            append = FALSE) {
  head <- paste("<table>\n<caption>", capt, "</caption>\n")
  cat(head, file= file, append= append)
  if (is.null(rownames(t))) {
    rownames(t) <- rep("", nrow(t))
  }
  tp <- rbind(c("<tr><td></td>", colnames(t)),
              cbind(unlist(lapply(rownames(t), function(x) {
                paste("<tr><td>", x)})), t))
  write.table(tp, sep= "<td>", file= file, , eol= "</tr>\n",
              row.names=FALSE,
              col.names=FALSE,
              append=TRUE, quote=FALSE)
  cat("</tr>\n</table>\n", file= file, append= TRUE)
}
