[R] Extract Data form Website Tables

[Rui Barradas]

Hello,

Maybe something like the following.

#install.packages("XML", dep = TRUE)

library(XML)

url <- 
"http://games.crossfit.com/scores/leaderboard.php?stage=1&sort=0&division=1&region=0&numberperpage=60&page=0&competition=0&frontpage=0&expanded=0&full=1&year=14&showtoggles=0&hidedropdowns=0&showathleteac=1&athletename="
data <- readHTMLTable(readLines(url), which=1, header=TRUE)

names(data) <- gsub("\\n", "", names(data))
names(data) <- gsub(" +", "", names(data))

data[] <- lapply(data, function(x) gsub("\\n", "", x))

str(data)


Hope this helps,

Rui Barradas

In looking at the source code of the website, I think I can go to here and maybe grab scores, but I am not sure if R can someone read them in from this and populate a data frame and subsequently grab data from every page.
