Run this code

# NOT RUN {
data(Master); data(Batting)

## add player's name to Batting data
Master$name <- paste(Master$nameFirst, Master$nameLast, sep=" ")
batting <- merge(Batting, 
                 Master[,c("playerID","name")], 
                 by="playerID", all.x=TRUE)

## batting and throwing
# right-handed batters are much less ambidexterous in throwing than left-handed batters
# (should only include batters)

BT <- with(Master, table(bats, throws))
require(vcd)
