Doing cricket analysis and web scraping in R using rvest #rstats

I modified the code used here (https://decisionstats.com/2012/04/07/cricinfo-statsguru-database-for-statistical-and-graphical-analysis/ ) with the code used here (http://reed.edu/data-at-reed/resources/R/rvest.html ) to get a more updated version of Cricket Analysis but using the rvest package by Hadley W Screenshot from 2015-05-12 13:55:03

Note you can change the url to make the records , the team , the type of record (batting or fielding)

I found it to be the third html table in the field by just testing it around

library(rvest)
page=html("http://stats.espncricinfo.com/ci/engine/stats/index.html?class=1;team=6;template=results;type=batting")
data %
 html_nodes("table") %>%
 .[[3]] %>%
 html_table()
