Examples

## 'hwc' was made like (commands repeated until sd was around 3):
sd(VES.BR <- round(rnorm(30, mean=mean(70:90), sd=3)))
sd(VES.BL <- round(rnorm(30, mean=mean(69:79), sd=3)))
sd(VES.SH <- round(rnorm(30, mean=mean(70:80), sd=3)))
sd(ROST.BR <- round(rnorm(30, mean=mean(160:180), sd=3)))
sd(ROST.BL <- round(rnorm(30, mean=mean(155:160), sd=3)))
sd(ROST.SH <- round(rnorm(30, mean=mean(160:170), sd=3)))
data.frame(COLOR=rep(c("black", "blond", "brown"), each=30),
 WEIGHT=c(VES.BR, VES.BL, VES.SH), HEIGHT=c(ROST.BR, ROST.BL, ROST.SH))

## 'hwc2' is similar but 'sd' was not controlled so it is usually not homogeneous

## 'hwc3' was made like:
set.seed(1683)
VES.BR <- sample(70:90, 30, replace=TRUE)
VES.BL <- sample(69:79, 30, replace=TRUE)
VES.SH <- sample(70:80, 30, replace=TRUE)
ROST.BR <- sample(160:180, 30, replace=TRUE)
ROST.BL <- sample(155:160, 30, replace=TRUE)
ROST.SH <- sample(160:170, 30, replace=TRUE)
data.frame(COLOR=rep(c("black", "blond", "brown"), each=30), 
 WEIGHT=c(VES.BR, VES.BL, VES.SH), HEIGHT=c(ROST.BR, ROST.BL, ROST.SH))
