rpart postscript graphics, Mac OS
I am running R on Mac OS X 10.2x. When I create
postscript graphics of rpart tree objects, a tiny part
of the tree gets trimmed off, even when it has only a
few terminal nodes. This happens even without fancy
but worse if fancy=T. (This doesn't happen with
boxplot, scatter plots, etc.) How do I fix this?

jpeg and margin text
Hi guys,
I use R 2.6.2 and Windows XP.
I’ve got the following question: I wrote a lot of text into the margin of a
plot. When I use the “jpeg”-function, only a little part of the margin text
is displayed in the final jpeg? Any ideas to change it?

Using minsplit and unequal weights in rpart
Dear r-help mailing list,
Is there a way to incorporate weights into the minsplit criteria in rpart,
when the weights are uneven? I could not find a way for the minsplit
threshold to take the weights into account, and when the weights are uneven
it becomes an issue, as the following example shows.
My current workaround is to expand the data into one in which each row is
an observation, but that

legend in multiple plot
Dear R users,
I'm making multiple plots within the same pdf page (par(mfcol = c(5,1)), and
want a legend for this at the bottom of all the plots. From previous mails
it has been suggested to use par(xpd=TRUE), increase the margin at the last
plot, and then draw the legend. However, when I do this, the last plot gets
smaller with the same amount I increase the margin with.
The problem seems to

dev.print() doesn't copy graphics in left margin
I've a plot which puts some text and lines in a wider than
normal left margin (using xpd=T). When I use dev.print() to
capture the plot to postscript, it faithfully duplicates the
plot except for the graphics in the left margin.
I can't duplicate this effect in a simple plot such as
plot(runif(10)), so I can't give you sample code.
Any idea what I'm doing wrong?

Plotting color.legend() outside of plot region
Dear List,
I am trying to plot a color.legend() in the right outer margin of my device region. I have read multiple threads on the subject and still can't get it right. I have stolen an example from one of the threads to demonstrate my problem. I have extended the outer margin using par(oma()), and have used par(xpd=NA) to tell it to plot in the device region. I can get the legend to plot

Working up examples of barplots with customized marginal items
Hello, everybody:
I'm back to share a long piece of example code. Because I had trouble
understanding the role of par() and margins when customizing barplots,
I have struggled with this example. In case you are a student wanting
to place legends or textual markers in the outer regions of a barplot,
you might run these examples.
There are a few little things I don't quite understand.

Legend in the outer margin
Dear Rs
I have a 3x3 multiple plot. I would like to have a overall legend in
the outer right margin.
From the help archive, I found that it can be done by setting
par(xpd=NA). However, I couldn't find the correct values
for x and y co-ordinates for the legend. Please find the code snippet below:
par(mfrow=c(3,3), mar=c(4,4,0.9,0.5), oma=c(1,2,2,4),cex.main=1.1)

reverse orientation of text in plot margins
Dear R users,
I am trying to reverse the orientation of axis labels and title in the right margin of a plot, so that they read from top to bottom. I know that this can be done using text() as follows:
par(mar=c(5,4,4,4)+.1)
plot(1:4,las=0)
par(new=T)
y <- rnorm(4)
plot(y,axes=FALSE,ann=FALSE,pch=17)

Plotting legend outside of multiple panels
Hello,
I have used layout() to produce to 2 plots on a page, leaving a plotting space above them. I would like "Legend", which will actually be a real legend, to be centered above the two graphs. Right now I am only able to position "Legend" above the second graph that I create... obviously I am stuck in its margin space.
Is there a way to draw the legend in the empty

losing x-label when exporting to PNG
I have a simple barplot that looks fine in the R

Rpart decision tree
Dear useRs:
I try to plot an rpart object but cannot get a nice tree structure plot. I
am using plot.rpart and text.rpart (please see below) but the branches that
connect the nodes overlap the text in the ellipses and rectangles. Is there
a way to get a clean nice tree plot (as in the Rpart Mayo report)? I work
under Windows and use R2.11.1 with rpart version 3.1-46.
Thank you.

plotting rpart objects, text.rpart, fancy option
I have created plots of rpart objects with the fancy option for text.rpart
("fancy" creates ellipses and rectangles and labels branches with splitting
criteria). The ellipses and rectangles are supposed to "interrupt" the tree
lines (as seen in Therneau and Atkinson 1997, page 48, Fig. 18,
http://www.mayo.edu/hsr/techrpt/61.pdf), but they do not, even when I use

pairs, par
Hi,
I posted over at R-help, and didn't get a response, but perhaps that
was the wrong forum for this question. I'm having some confusion over
the coordinate system after using pairs. I'm not interested in the
content of the actual pairs plot, although the number of pairs seems
to matter a bit. I'm purely interested in knowing where subsequent
points will be plotted on the

[FORGED] Re: axis() after image.plot() does not work except if points() is inserted between
Hi
I believe this is a clipping bug in the 'graphics' package.
A simpler version of the problem is this ...
plot(1:10)
mtext("margin-label", side=2, at=9, las=1, line=1, adj=0)
par(mfg=c(1,1))
## Only the text within the plot region is drawn
mtext("margin-label", side=2, at=9, las=1, line=1, adj=0, col="red")

Change margin size of complex barplot
Dear R-help members,
with the help of one of you the following R-Code was developed. No I have the (probably simple) problem that I want to increase font size of "text" and "ylab" names from 1 to 2. Unfortunately I'm not able to adjust the margin so, that the plot is appers complete (all names readable) on a 8:14 Inch scale plot.

plotting rpart objects - fancy option
Hi all,
I'm trying to create nice plots of rpart objects. In particular, I'd
like to use the "fancy" option to text() that creates ellipses and
rectangles at the splits and endnotes, respectively. This worked fine in
the past, but now the ellipses do not interrupt the original tree lines
anymore but overlay them (see attached ps file). I'd like it to look the
way Figure
