Hi Folks, I've got a question regarding the 'quantreg' package maintained by Roger Koenker: I tried to produce LaTeX tables using the longtable and dcolumn options as decribed in the manual, but the function latex() doesn't seem to react on _any_ other options than 'digits' and 'transpose'. To reproduce these results the following minimal example may be used:

Dear Sir /Madam I have a problem in installing quantreg package. I recieve this message “package ‘quantreg’ is not available (for R version 2.13.1). Thanks in adavance for the help.

Dear R-mailing list, I would like to overlay to two quantreg coefficients plots. I have plot(summary(rq(ff~tipo,tau = 1:49/50,data=Spilldata))) plot(summary(rq(ff~tipo,tau = 1:49/50,data=Spilldata1))) Is there a possibility to display the two in the same graph? Thank you so much!!! Christian [[alternative HTML version deleted]]

I am trying to install the "quantreg Package" on MacOSX. When I choose CRAN mirror, it gives me the error: Error in read.dcf(file = tmpf) : Line longer than buffer size In addition: There were 44 warnings (use warnings() to see them) Is there any known current problem with this package?

Hi All: I tried to download and install "quantreg" (a package for doing quantile regression) from CRAN. When I ran install.packages ("quantreg") within an R session, I got the following error message: <----Beginning of error message ---> * Installing *source* package 'quantreg' ... ** libs g77 -mieee-fp -fPIC -O2 -g -pipe -march=i386 -mcpu=i686 -c akj.f

Hi - I also posted this on r-sig-ecology to little fanfare, so I'm trying here. I've recently hit an apparent R issue that I cannot resolve (or understand, actually). I am using the quantreg package (quantile regression) to fit a vector of quantiles to a dataset, approx 200-400 observations. To accommodate some autocorrelation issues, I have to assess significance with

Mike, Do something like: require(rms) dd <- datadist(mydatarame); options(datadist='dd') f <- Rq(y ~ rcs(age,4)*sex, tau=.5) # use rq function in quantreg summary(f) # inter-quartile-range differences in medians of y (b/c tau=.5) plot(Predict(f, age, sex)) # show age effect on median as a continuous variable For more help type ?summary.rms and ?Predict Frank ------------

Hi, I've implemented the KhmaladzeTest for my linear quantile regression model for the location-scale shift hypotesis as follow: >formula=r ~ div + pe + por >Ktest=KhmaladzeTest(formula,nullH="location-scale") > Ktest $nullH [1] "location-scale" $Tn [1] 2.125804 $THn div pe por 0.7972984 1.4432325 0.7107914

Dear all How can I obtain the data from the function "rearrange" in package quantreg More especifically, based on the example below (available in the help of the rearrange function), how can I access the data generated by "rearrange(zp)" ? data(engel) z <- rq(foodexp ~ income, tau = -1,data =engel) zp <-

Hello everybody! I am currently using the quantreg package on R 2.2.1. for my diploma thesis and want to create plots with plot.summary.rqs, which should work like this: Usage: plot.summary.rqs(x, nrow=3, ncol=2, alpha = 0.1, ols = TRUE, ...) Arguments: x: an object produced by rq() fitting nrow: rows in mfrow ncol: columns in mfrow alpha: alpha level of

I have recently started using R and want to use the quantreg (and sparseM) packages. I downloaded the .tar files for each, and placed the subsequent folders into the library folder in the frameworks/R.framework/ resources/library folder with all the other packages. When I try to load either package from the package manager window I get: Loading required package: SparseM Error in

Hi, I have used package quantreg to estimate a non-linear fit to the lowest part of my data points. It works great, by the way. But I'd like to extract the predicted values. The help for predict.qss1 indicates this: predict.qss1(object, newdata, ...) and states that newdata is a data frame describing the observations at which prediction is to be made. I used the same technique I used

A new version of the quantile regression package (quantreg 3.09) is now available on CRAN. The new features include: 1. a new fitting method "fnc" for rq() which allow the call to specify linear inequality constraints on the coefficients. 2. an anova() function for rq objects that implements several F-like tests for quantile regression models at a given quantile, and other F-like

Roger, I have run gfortran -c -fsyntax-only -fimplicit-none -Wall -pedantic rqbr.f in the src folder of quantreg. There are many warnings about defined but not used labels. Also two errors such as "Symbol ?in? at (1) has no IMPLICIT type". And warnings such as: Warning: "Possible change of value in conversion from REAL(8) to INTEGER(4) at ..." No offense intended but

I've just installed R 1.0.8 (for Windows) and I tried to install the package Quantreg directly from Cran but it's not in the list of downlodable packages. I tried also downloading the zip file and then install it but there is an error. How can I do it? Thank you [[alternative HTML version deleted]]

Quantreg package allows to plot the summary of models derived by quantile regression at different taus. The plot shows the parameters variation by varying taus: intercept and slope (for a linear model). Together with these values even confidence intervals may be plotted, based on the threshold given within the summary (e.g. alpha=0.01 equals 99% CI). However the graphic even plots the mean of
