Gurus:
I have a new version of my quantreg package with minimal changes, mainly to fix
some obscure fortran problems. It fails R CMD check —as-cran with the error:
Running examples in ‘quantreg-Ex.R’ failed
The error most likely occurred in:
> base::assign(".ptime", proc.time(), pos = "CheckExEnv")
> ### Name: plot.rqss
> ### Title: Plot Method for rqss Objects
> ### Aliases: plot.rqss plot.qss1 plot.qts1 plot.qss2 plot.summary.rqss
> ### Keywords: regression smooth iplot
> > ### ** Examples
> > n <- 200
> x <- sort(rchisq(n,4))
> z <- x + rnorm(n)
> y <- log(x)+ .1*(log(x))^2 + log(x)*rnorm(n)/4 + z
> plot(x,y-z)
> fN <- rqss(y~qss(x,constraint="N")+z)
*** caught segfault ***
address 0x0, cause 'invalid permissions’
However, if I install it and run example(plot.rqss) it runs normally. If some
kind soul knows or is willing to dig into this to learn what the problem is, I
would be most grateful. The package is available from
http://www.econ.uiuc.edu/~roger/research/rq/quantreg/quantreg_5.99.tar.gz.
TIA,
