Hi,
It's rather statistical question than R-question.
There is some linear correlation but the picture plot(a,b) +
abline(lm(b~a)) is quite crowded in the left lower corner. The
picture plot(log(a), log(b)) + abline(lm(log(b)~log(a)) is much
nicer (Milky Way). Is it correct to use the second

Hi, Ted.
Thanks for your reply. It helped. I have further a bit of questions.
It may be that lm(log(b) ~ log(a)) is, from a substantive point of view,
a more appropriate model for whetever it is than lm(b ~ a). Or it may
not be. This is a separate question. Again, Spearman's rho is not
