How can I scrape this webpage in R?

Question

I'm trying to scrape the following webpage in R using the XML, RCurl, or httr libraries: http://accuscore.com/fantasy-sports/nfl-fantasy-sports/Rest-of-Season-RB

The webpage opens correctly in my browser. Here are my attempts to scrape the webpage:

library("XML")

#this works fine (QB projections) 
qb <- readHTMLTable("http://accuscore.com/fantasy-sports/nfl-fantasy-sports/", header=1)$fantasy_table

#this does not (RB projections) 
rb <- readHTMLTable("http://accuscore.com/fantasy-sports/nfl-fantasy-sports/Rest-of-Season-RB", header=1)$fantasy_table

library("RCurl")
htmlParse("http://accuscore.com/fantasy-sports/nfl-fantasy-sports/Rest-of-Season-RB")

library("httr")
GET("http://accuscore.com/fantasy-sports/nfl-fantasy-sports/Rest-of-Season-RB")

I receive the following error with readHTMLTable and htmlParse: "Error: failed to load HTTP resource". With GET, I receive a status code 404, which suggests that the resource could not be found and that there may be a mistake in the way I'm sending the request. Given that I can open the webpage in my browser, I'm not sure what the problem is. Maybe it's a different kind of file than the functions are expecting? Any ideas?

Ideally, the scrape would be for all 146 entries (not just the first 25).

Works fine for me with RCurl

require(RCurl)
readHTMLTable(getURL("http://accuscore.com/fantasy-sports/nfl-fantasy-sports/Rest-of-Season-RB"), header = 1)
> head(readHTMLTable(getURL("http://accuscore.com/fantasy-sports/nfl-fantasy-sports/Rest-of-Season-RB"), header = 1)$fantasy)
