webscraping data tables and data from a web page

I am trying to webscrape real time streaming data tables and data from a web page I tried:

library(XML)
webpage  <- "http://www.investing.com/indices/us-30"

tables <- readHTMLTable(webpage )
n.rows <- unlist(lapply(tables, function(t) dim(t)[1]))

tables
n.rows

but I get an error.

Thank you for your help.

I'm actually proud of myself for getting this to work (I have been trying to get my head around these kinds of things for a long time now....)

library(rvest)
url4 <- "http://www.investing.com/indices/us-30-historical-data"

yourdata <- url4 %>% read_html() %>% 
html_nodes(xpath = '//*[@id="results_box"]/table[1]') %>% 
html_table()   

yourdata <- as.data.frame(yourdata)
