The data came from http://www.personal.rdg.ac.uk/~snsgrubb/athletics/agegroups.html which included a calculator to compare results.
data(best.times) attach(best.times) by.dist = split(best.times,as.factor(Dist)) lm(scale(Time) ~ age, by.dist[['400']]) dists = names(by.dist) lapply(dists, function(n) print(lm(scale(Time) ~ age, by.dist[[n]])))
