Boxplots are a nice way to compare the three sample sets of the Shoot-out 2012 data files.
There is a category variable (Set) in the data frame with the labels (Cal = Training Set, Test = Test Set and Val = Validation Set).
# IMPORTING THE SAMPLE SETS #
shootout2012.raw<-read.csv("Shootout2012_R.csv",header=TRUE)
# ORGANIZING THE DATA-FRAME #
NIT<-shootout2012.raw[,4:375]
Active<-shootout2012.raw[,3]
Set<-shootout2012.raw[,2]
shootout2012<-data.frame(Set=I(Set),Active=I(Active),
+ NIT=I(NIT))
names(shootout2012)
# “Set” “Active” “NIT”
attach(shootout2012)
boxplot(Active ~ Set,main=”Shootout 2012″,xlab=”Sample Sets”,
+ col=”grey”)
aggregate(Active ~ Set, summary, data=shootout2012)
