For the following model, library(vcd) arth.polr <- polr(Improved ~ Sex + Treatment + Age, data=Arthritis) summary(arth.polr) where Improved is an ordered, 3-level response I'm looking for a *simple* way to test the validity of the proportional odds assumption, typically done via a score test for equal slopes/effects over the predictors. I do find a po.test= option in the repolr package

I'm pretty sure that I did everything right, but my R is just not drawing the mosaicplot that I want, and there is also no error messege, looks like this right now: > mosaicplot(arthritis) > mosaicplot(~ sex + treatment + improved, data = arthritis, color = TRUE) > -- View this message in context: http://r.789695.n4.nabble.com/problems-with-mosaic-plot-tp3090128p3090128.html Sent

In an Rweave tutorial written for possibly naive R users, I felt it necessary to explain why table() had to be used inside with(), whereas other tools like xtabs() had a data= argument. with() is quite nice for such cases, but it seems an unnecessary thing to learn right off. Before I turn this question into a request for R-devel, is there any inherent reason why it might be hard to add a

If there are any other users who use AHRQ's SAS code comoanaly2010 and comformat2010 to create comorbidity variables, I thought you might be interested in the following PRELIM code we wrote to mimic its functionality in R. It seems to yield similar results, but may contain errors. Please feel free to comment (kindly) or enhance. I'm sure there are better ways to skin this cat, but we at

I have a figure on screen with a legend. I want to copy this image to EPS, and use: dev.copy2eps(file="file1.eps", width=5, height=5) The legend that looks OK on screen doesn't look OK in the PostScript image: the text extends out of the box. I try adding a fontsize command: dev.copy2eps(file="file1.eps", width=5, height=5, pointsize=5) This options seems to

HI! I'm using the function dev.copy2eps to store a plot into a file. How can I change the default name of the file and the path where the file should be created ?

In http://tolstoy.newcastle.edu.au/R/e2/help/06/10/3064.html a method was given for converting a frequency table to an expanded data frame representing each observation as a set of factors. A slightly modified version was later included in the NCStats package, only on http://rforge.net/ (and it has too many dependencies to be useful). I've tried to make it more general, allowing an input

The definition for dev.copy2eps contains the following line: oc$paper <- "special" The result of this is that the output will be placed in the left bottom corner of the page. Even though dev.copy2eps is meant for creating files that are to be included into other documents, you might want to print the figure directly, just to see how it will look on paper. (Of course, this will

Hi, a colleague of mine encountered some unexpected behavior regarding the postscript output from R. It's difficult for me to tell whether or not this is an R problem or a ghostview/gv/interpreter problem. Just to note, I think it's exactly the same situation reported here: http://finzi.psych.upenn.edu/R/Rhelp02/archive/25436.html The following code produces a working plot (no

On a RedHat 7.3 system with R-1.6.1, I did this > x11(width=3.5,height=4,colortype="gray") Then plotted (with matplot) a nice looking no-color graph on the screen, then I did this: > dev.copy2eps(file="test.eps",height=4,width=3.5) I was surprised that the output in the eps file included the colored lines from the plot, even though the screen device was set to

Hi, I'm trying to get 2x2 (or other layouts) of cd_plot from the vcd package. I have tried the usual commands like layout, par(mfrow...) etc and but cd_plot seems to ignore them and send the plotting window back to 1x1. I have also tried turning off the pop and newpage options in cd_plot but I still can't get multiple cd_plots into a plotting window. Any suggestions would be greatly

Hi all, When I plot some graph with cyrillic (namely russian) titles it looks ok, but after saving this figure as eps file I get damaged title fonts. The command dev.copy2eps was used in the following manner: dev.copy2eps("test.eps") or, for example dev.copy2eps("test.eps",family='NimbusSan') What is wrong? I use R 2.6.0 under Windows. Any help will be appreciated.

Hi there, if I copy an x11() graphics device to an eps-file (with dev.copy2eps()) the font in the legend is very large and doesn't fit to the legend box in the eps-file (same with a postscript file). I'm not sure if this is a R problem rather than a ghostscript one. But is there a way to solve this problem in R or depends this on my ghostscript installation? System: R Version 1.2.3 on

I want to plot and then save graphs in a loop. The problem is that the graphs take too long to plot. Execution jumps to the save command (dev.copy2eps) before the plotting has finished, and so the wrong graph is saved. I works fine if I step through slowly command at a time, but I want to do it programmatically. How can I tell R to wait for the graph to finish? I have tried Sys.sleep, but that

I want to use a shortcut for copying figures to EPS. I defined this function in .Rprofile: ps <- function(file="Rplot.eps", width=7, height=7, ...) { dev.copy2eps(file=file, width=width, height=height, ...) } This doesn't work: > data(cars) > plot(cars) > ps() Error in device(...) : Object "width" not found Can anyone tell me

Hi, Am using R 2.13.1 on Linux (Fedora). Is anybody else having problems with dev.copy2pdf xyplot output with the pch=1 (open circle) symbol? The symbols come out as "q" in the PDF. dev.copy2eps produces the correct results as does cairo_pdf. Other symbols produced with dev.copy2pdf seem ok. Thanks, Selwyn

Earlier today I posted a problem importing an R graph into a LaTeX file of seminar class: specifically, the graphic was showing up rotated 180 degrees, along with the rest of the page it was on. In a real victory for open-source software, I got lots of responses with three distinct approaches, each of which appears to solve the problem. Try getting fast, correct help from Microsoft on a Sunday

Dear all, I am new to this list and, unfortunately, could not provide help to anyone as yet. I hope I can do so in the future, though! Until then, I am grateful for helpful hints from you more experienced users. For use in an upcoming publication, I generated an eps figure from my x11 window under Debian Linux with dev.copy2eps. It contains 28 line plots with 2 lines each, one solid and one

Hello list, I have encountered a problem trying to save graphs using the R-graphics menu: File|Save as. The menu suggests that files may be saved as either Metafile, Postscript, pdf, png, bmp, jpeg. When I specify any of those file formats a menu comes up requesting a file name. After providing a name R invariably hangs and has to be restarted. I am able to save files under the various
