splom pairs and groups argument
Hello,
I'm trying to pull off a certain graph using splom, and can't quite get my panel functions right.
Basically, the equivalent using pairs would be something like this (using iris data set as an example):
panel.corval <- function(x, y, digits=2, prefix="", cex.cor,col,pch)
{
usr <- par("usr"); on.exit(par(usr))
par(usr = c(0, 1, 0, 1))

font size for pairs()
Dear R-Help,
I'm having some trouble with the font size in the pairs() function. It
seems to be impossible to alter the font size for the variable labels that
run down the diagonal. I've tried all the cex.??? parameters to no avail.
I'm using R0.65.0 on windowsNT. If the simple answer is to upgrade to the
latest version of R, then please accept my humble apologies for troubling you.

pairs(), expression in label and color in text.panel
Hello,
I'd like to add custom labels to my pair() plot. These
labels include math expression but they aren't correctly
displayed...
Further, I want that the boxes for the text.panel (diagonal)
have an other background color (grey80). Is that generally
possible? If yes how do I have to set it?
What I've so far is:
panel.cor <- function(x, y, digits=2, prefix="",

Need help putting histograms on the diagonal of a splom plot
Hello,
I am in need of help in putting histograms on the diagonal of a plot
produced with splom().
The plot matrix I am trying to produce is to have standard scatterplots
in the upper-left triangle, contour plots in the lower-right triangle,
and histograms on the diagonal. I have a function that does the first
two, but the histograms on the diagonal has been beyond my ability.

How to identify the two largest peaks in a trimodal distribution
Hello all
I'm trying to do a simulation that involves identifying the minimum
point between two peaks of a (usually) bimodal distribution. I can do
this easily if there are only two peaks:
CnBdens<-density(Ys/Xs) #probability density function for ratio of Ys
to Xs
for(p in 1:512) ifelse(CnBdens$y[p]>CnBdens$y[p-1],peak1<-p,break)
#identifies first peak in probability

How to add the variable name to a qqplot or densityplot in the diagonal of an splom?
splom() doesn't complain here, but writes no names in the diagonal
boxes. What am I missing?
I believe that I need to add something like grid.text(x, ...) to the
diagonal panel, but I don't know how to get it cycle through the
column labels. And should
varname.col = 'blue', varname.cex = 1
be inside the diag.panel() function?

Comparing switchpoints from segmented
Hello everyone
Not strictly an R question but close... hopefully someone will be able
to help. I wish to compare the switchpoints in two switchpoint
regressions. The switchpoints were estimated using the segmented
library running in R, and I have standard errors for the estimates. I
initially thought I could just bootstrap confidence intervals for the
difference between the switchpoints,

Block factor as random or fixed effect?
People
I apologise for asking a general stats question, but I'm at a bit of a
loss as to what to do following some hostile referees' comments. If I
have a fully randomised blocked design, with only three blocks, should
I treat block as a random or fixed effect? I have read comments about
not treating block as a random effect if the number of blocks is less
than 6 or 7: is this

"pairs" with same xlim and ylim scale
Hi list,
I have a function which basically is a wrapper of pairs with some useful panel
functions. However, I'm having trouble to pass the "xlim" and "ylim" into the
function so the x and y axes are in the same scale and 45 degree lines are
exactly diagonal. I've looked at some old posts, they didn't help much. I
think this is b/c I have multiple panel

Limiting size of pairs plots
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

font sizes for row.names of dendograms
Dear R
I recently performed a cluster analysis. It produced the dendogram no
problem but unfortunately the font size of the row.names were all cluttered
due to their large size
So I tried to change the font size using
plclust(cluster.results, labels=iris$specie, cex=0.8)
and R came back to me saying
Error in plclust(cluster.results, labels = iris$specie, cex = 0.8) :

exporting high quality graphics from R in Mac OSX
Hi there
The default option for saving graphics from R (1.9.1) on my Mac is as a
pdf file. If I open the file in Acrobat reader it looks really good and
crisp, and is obviously saved as vector graphics, since I can zoom in
as much as I like and it continues to look really nice. If I import it
into MS Word (from office 2000), or Textedit, however, it imports it as
a bitmap and unless I save

cex.axis in boxplot (PR#2628)
Hi,
the graphical parameter "cex.axis" does not have any affect for "boxplot":
data(iris)
boxplot(iris[,1:4], ylab="y", cex.lab=2, cex.axis=2)
The patch is simply adding "cex.axis" to the search for axis relevant
parameters in "bxp":
ax.pars <- pars[names(pars) %in% c("xaxt", "yaxt", "las",

changing font size for y-axis factor labels
I am trying to reduce the font size for y-axis labels, not ylab, but the
actual categorical names. I have tried cex, cex.axis, cex.lab, font,
but none seem to do the trick. Any ideas? thank you.

persp(), axis font size
Is there a way to adjust the font size for axis labels when using
persp()? The parameter cex works for adjusting the global font size, but
I can't seem to make cex.lab or cex.axis work for adjusting these
values independently. Or, is there a preferred method for making surface
plots in R?
I'm using R version 1.8.
Thanks,
