Having problems with quantreg
Hi All, I'm still having significantly difficulty getting the quantreg library running in R. I'm running R on MEPIS using the debs created by Dirk Eddelbuettel and placed in apt testing.

Quantreg - 'could not find function"rq"'
Hi all, I'm having some troubles with the Quantreg package. I am using R version 2.10.0, and have downloaded the most recent version of Quantreg (4.44) and SparseM (0.83 - required package). However, when I try to run an analysis (e.g. fit1<-rq(y~x, tau=0.5)) I get an error message saying that the function "rq" could not be found. I get the same message when I try to search

quantreg installation and conflicts with R 2.15.2
I recently lost the partitions on my hard drive (second time in 6 months) so I had to have our IT folks image all my files over to a new drive. I completely reinstalled R (now 2.15.2) and all my libraries to my computer (Dell Latitude running Windows 7). A few of my previous workspaces (created with R 2.14.1) can't be restored, reporting an error similar to the one I get when I try to

2 problems with latex.table (quantreg package) - reproducible
Dear all, When using latex.table from the quantreg package, I don't seem to be able to set table.env=FALSE: when I don't specify caption (as I think I should, when understanding the R help rightly(?)), I get an error message, and when I do so, of course I get one, as well. The funny thing is, that a table is indeed produced in the first case, so I get a nice tabular, but as I'm using

rqss help in Quantreg

RuleFit & quantreg: partial dependence plots; showing an effect
Dear List, I would greatly appreciate help on the following matter: The RuleFit program of Professor Friedman uses partial dependence plots to explore the effect of an explanatory variable on the response variable, after accounting for the average effects of the other variables.

Memory issues on a 64-bit debian system (quantreg)
Rers: I installed R 2.9.0 from the Debian package manager on our amd64 system that currently has 6GB of RAM -- my first question is whether this installation is a true 64-bit installation (should R have access to > 4GB of RAM?) I suspect so, because I was running an rqss() (package quantreg, installed via install.packages() -- I noticed it required a compilation of the source) and

how to extract predicted values from a quantreg fit?
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

plot(summary) quantreg - Not all outputs needed
Hi Folks, I am currently trying to present some results I obtained by using the quantreg package developed by Roger Koenker. After calculating fit<-summary(rq(Y~X1+X2, tau=2:98/100) ) the function plot(fit) presents a really nice the results by showing the values for all "regressors" in the given interval tau. But in my case, I only need the output of a single variable, say X1 and I

Quantreg-rq crashing trouble
Hi I am using the quantreg package for median regression for a large series of subsets of data. It works fabulously for all but one subset. When it reaches this subset, R takes the command and never responds. I end up having to kill R and restart it. It appears to be something with the particular data subset, but I can't pinpoint the problem. Here are some details Operating system:
