I used the codes below trying to fit a model at .95 c.i. of size relationship but it fails. library(quantreg) range(len$length) range(len$preyl) x<-rq(len$preyl~len$length,tau=0.95) plot(x, type="b", xlab="length (cm)",ylab="preyl (cm)",ylim=c(5,35), xlim=c(10,100), data=len) Cheers, Nuru -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
