Hey, I'm trying to create an image file with the results of a regression analysis. In TeX, the line would be something like: $ size = 0.34 + 4.3 var_1 $ Can I create a plot window with just this line in it? I tried playing around with plot.new() or dev.new(), but didn't really find something that worked. Thanks in advance, Alex -- alexx at alexx-fett:~$ vi .emacs

Hi all, I'm trying to generate a plot containing a scatterplot, with marginal densityplots for x and y. However, when I try to generate a vertical densityplot, I get the message "warning: can't clip to rotated viewport", and nothing shows up. I'm probably misunderstanding how viewports are meant to be used, so if someone could give me a hint, I'd be most grateful. my

I'm presumably missing something very obvious, but how does one use the key.opts argument in labcurve (via Ecdf)? In this example, I want the key to be big and have a blue background, but it isn't and doesn't. ch <- rnorm(1000, 200, 40) sex <- factor(sample(c('female','male'), 1000, TRUE)) Ecdf(~ch, group=sex, label.curves=list(keys=c("f",

I recommend instead of no border, that you use a border with the same color as the fill. I do this in the likert functions in the HH package.

Dear R-users, I want to draw a barplot with beside=TRUE. One halve of the bars are drawn with a border, while the other halve are drawn without a border (i.e. filled bars vs. non-filled bars next to each other). Because borders are drawn around the bars, doing this leads to one halve of the bars being wider than the other halve, expanding across the 0-point of the y-axis. This problem emerges

I am having a problem in editing a grob. It works ok if I try to shift the grob using npc coordinates but if I do the same thing using native coordinates the grob disappears. What is wrong? library(grid) grid.newpage() # create viewport pushViewport(viewport(xscale = c(100,200), name = "X")) # draw vertical line grid.lines(150, 0:1, default.units = "native", name =

Dear R-users, I would like to add a legend at the bottom of pairs plots (it's my first use of this function). With the plot function, I usually add some additional space at the bottom when I define the size of the graphical device (using mar); grid functions then allows me to draw my legend as I want. Unfortunatley, this technique does not seem to work with the pairs function as the
