...4 different treatments the variables undergo. I also have 1 column with year the data was recorded. I want to create a bar plot that plots all 8 variables grouped by treatment and year. I've tried creating subsets of each of the variables, no luck. My variables are arranged similar to this: Vascular.plants Solid.rock Gravel.and.cobbles 72.5 1.0 5 67.5 2.0 6 67.5 2.5 9 59.0 2.0 25 [[alternative HTML version deleted]]

Dear all, I'm performing a detrended correspondence analysis on vascular plant community data (296 species), and I have a question on the species scores projected in the ordination diagram. When I run a ordiplot all species are projected in the output graph, but I'd like to restrict the number of species plotted in the final graph. Some species are so rare in the da...

What is the best way to report the standard error when publishing Kaplan-Meier plots? In my field (Vascular Surgery), practitioners loosely refer to the "10% error" cutoff as the point at which to stop drawing the KM curve. I am interpreting this as the *standard error of the cumulative hazard*, although I'm having a difficult time finding some guidelines about this (perhaps I am not searc...

...kage because I often deal with repeatedly sampled pairs of data from the same source, and my reading (and my statistician) tells me that GEE is an appropriate method for that type of data set. I’m using the geeglm program from the geepack download. My data is correlated data from two estimates of vascular permeability in a rat model of cerebral tumor. One estimate, the MRI estimate, can be conducted non-invasively and repeatedly. The other estimate, the QAR estimate, can be done just once since it involves sacrificing the animal. The MRI estimate needs to be characterized as to its correlation wi...

...e request storm. It looks like winbindd has been re-architected to prevent blocking like this, but I haven't installed the latest version in order to test that theory. Would turning off WINS request logging alleviate the problem? Is such a thing even possible?

Hi there folks I have R 1.3.0 running on Red Hat Linux 7.1 with GhostView 3.5.8. When I produce a file like: > bitmap("foo.pdf", type="pdfwrite") > plot(foo) > dev.off() and then try to read it with gv, I get an unrecoverable error and nothing displayed. Any help as to whether this ***should*** work would be appreciated. cheers, John -- John Williams
