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...

quantreg installation and conflicts with R 2.15.2

...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 load "quantreg" package which requires
"SparseM" (see below). So, not only will "quantreg" not load but some of
my workspaces can''t be restored when being loaded (see below). Not sure
about what this is about. I asked Roger Koenker, the package maintainer,
but he is on t...

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 observation...

Overlay two quantreg coefficients plots

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!!!

Re: Quantile Regression/(package (quantreg))

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

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...

R memory issue / quantreg

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 randomization. The problem is that I consistently
observe what appears to be a memory problem causing an R cra...
