I would like to analyze XML data from MLB's website. I do the following steps:
library(XML) dat<-"http://gd2.mlb.com/components/game/mlb/year_2007/month_05/day_02/gid_2007_05_02_arimlb_lanmlb_1/inning/inning_1.xml"; example<- xmlTreeParse(dat, useInternalNodes=T) ex<-xpathApply(example, "//inning", xmlToList) #could also use "//atbat" This brings information from the first inning of the Arizona/LA game played on 5/2/2007 into R. Now that I have it in R, I don't understand how to 'get at' the data. For example, how could I calculate the average start speed ( [[1]]$top$atbat$pitch["start_speed"] ) of all pitches thrown in the inning?
