[R] how to proof the trend of two columns of data?

[David L Carlson]

The list does not assist with homework problems. If this is not a class assignment, you should be more specific about what you have tried and provide a reproducible example (a sample of the real data or some made-up data that has the same columns and data types). In the meantime you could also try the following R command:

> ?kruskal.test

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?
