If you use ?lm, it's the residuals that should be normally distributed,
not age.
You can also use ?glm with a binomial link, in which case you should
recode type as white/not white.
Hope this helps,

, which statistic method should use to prove the trend relationship
between them, for example, the older has more probability of white hair
type? Are there any existed R package to figure out this situation?
