[R] Quanteg problem in R

[Garkuwa, Nuru Adamu]

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
