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 kind of picture for illustration ? I use Spearman's rho and it's the same for both linear models. Regards, Kate. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
