Quantile Regression Error

Hi,

I installed the package quantreg, but something is wrong. I have no Fortran
knowledge, but from programming background it seems that the code as some 
bug/inconsistency. I could only find the file rq.f (see error message below)
in the directory created
after untar the package (~/quantreg/src/rq.f). I edited the file and in 
fact there's a bunch of "go to ..." statements where things are going wrong.

Those are warnings coming from g77 but this is allowed Fortran (if perhaps
not very good Fortran).  You will get warnings from g77 from quite a few
CRAN packages, but in this case I get warnings from Sun's f77 too.

I believe there's nothing "missing" in my o.s. and/or applications. I was
able to install the survival analysis package error free.

Any ideas? Thanks in advance to all for your inputs.

The problem is actually in the output you sent (thanks):

library(quantreg)

Error: dynamic library `Quantreg' not found

Note the case difference. quantreg/R/zzz.R contains

".First.lib" <- 
function(lib, pkg) {
   library.dynam("Quantreg", pkg, lib) }

and you need to replace "Quantreg" by "quantreg". This does not matter on a
DOS file system which is what the submitter used (on Windows 98, I
believe), and indeed the files are in DOS format.

This then works for me. (There is also a line in R/rq.R,

        if(!is.loaded(symbol.For("rq")))
                dyn.load("rq.dll")  #Changed(Kjetil). May need rewording
for non-windows systems 
that should be removed in R.)


I was going to suggest it would be better to contact the porter rather
than this list, but he has not given his email address anywhere in
the files (it is usually in the DESCRIPTION file).  So Kjetil,
quantreg_2.0-2, please. (If you can, use LF-terminated file: the simplest
way I know on Windows is to use zip -ll and then unzip.)
