quantreg installation and conflicts with R 2.15.2 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...

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?

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...
