Focus on a sub-panel of a splom with trellis.focs() -- return coordinate of sub-panel, or names of variables therein
Hi,
I'd like to be able to generate a splom plot in R and then use my mouse to click on one of the sub-panels (panel.pairs, specifically) and have R return either the coordinates of that sub-panel, or even better, the names of the corresponding variables plotted in that sub-panel.
Here's an example to work with:

Putting splom in a function
Hello R list,
I have a little problem with splom. I'd like to wrap it in a
function, for example:
multi.scatterplot <- function(data,groups,cols,colors) {
splom(~data[,cols], groups = as.symbol(groups), data = data, panel
= panel.superpose, col=colors)
}
and then call it like in
multi.scatterplot(iris,"Species",1:4,c("green","blue","red"))

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))

Splom plot:how to plot with different symbols?
Hi,
Kindly let me know if I posted a wrong question in the forum.
I want to draw a splom plot with different symbols in plot. My command is as
follows:

panel = panel.superpose,
key = list(title = paste(splomLoop,"Programs of Hog Analysis (Sorted by

Lattice: How to color the data points in splom() according to the panel they are plotted?
Dear ExpeRts,
I have the scatter plot matrix as given below. I would like the different "sub-plots" in the scatter plot matrix to be colored differently. How do I get all points shown in the upper-left plot (on position (1,1) in the scatter plot matrix) to be plotted in blue, and the points shown in the plot to the right (on position (1,2) in the scatter plot matrix) to be plotted in

Lattice: Histogram in splom diagonals
Dear list, I want to plot several variables with splom and in the main
diagonal, instead of the variable names, I'd like to plot an histogram of
corresponding variables. Searching I did not find the correct syntax, only
some tips in an old post in the list, but this comments help to plot only
density lines instead of histograms. I had some code, but it fails to plot

FIX: pscales=list(...) and splom
Dear R Users,
When plotting with "splom" I tried to use the pscales=list(...) feature
Unfortunately it didn't work at all. Instead the scales always were
suppressed.
So I looked at the source of panel.pairs and found:
"draw <- is.numeric(pscales) && pscales != 0"
which rather has to be:
"draw <- is.list(pscales) || (is.numeric(pscales) &&

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.

circular reference lines in splom

I'm stumped. I'd like to create a scatterplot matrix with circular

Lattice: splom plots for different factors with correlation in lower.panel
Hello list,
I am looking to create a figure for my dataset using splom, where there is a
splom subplot for each level of a factor within, for example, a 2x2 layout.
For each subplot, I wish to put the r-value between each variable pair in
the lower panel. The code I have thus far is below, using the iris dataset
so that it is reproducible. This almost does what I want, but for some

Putting regression lines on SPLOM
Sorry Folks,
I'm sure I could suss out the answer myself but I need it
soon ... !
1. Given a set of 4 variables X,Y,Z,W in a dataframe DF, I make
a scatter-plot matrix using splom(DF).
2. I do all regressions of U on V using lm(U~V), where U and V
are all 12 different ordered pairs from X,Y,Z,W.
3. Now I would like to superpose the regression lines from (2)

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?

Lattice Groups
Hi all,
I'm trying to achieve a few things using the lattice package but am failing miserably.
I am plotting side by side box plots and using a grouping variable, e.g.
cols <- c("Sepal.Width", "Petal.Length", "Petal.Width")
stackedData <- stack(iris[, cols])
df <- data.frame(y = stackedData$values, x = rep(iris$Species, 3), which = gl(3,

Lattice graphics on Mac OS X
Hi, everybody.
I just started using R on Mac OS X. I'm trying both of Carbon and
Darwin version. I used to use S-PLUS on Linux and want to use splom to
do multi-plot.
I looked at both Carbon and Darwin version, but Carbon version doesn't
seem to have Lattice library. I downloaded the binary for Darwin
version. I have XDarwin/OroborOSX installed on my Mac's (G4 Powerbook

lattice key in blank panel
Somewhere I've seen an example of an xyplot() where the key was placed
in a location of a missing panel. For example, if there were 3
conditioning levels, the panel grid would look like:

In this (possibly imaginary) example, there were scatter plots in
locations 1:3 and location 4 had no conditioning bar at the top, only
the key.

splom, plotmath: how to add three lines of information with alignment?
Dear expeRts,
I would like to create a scatter plot matrix with splom(). The lower panel should
contain some additional information about the samples shown in the upper panel
plot, see the splom() call below. Now two questions came up:
(1) The lower panels show "tau" and "alpha" on top of each other. How can I plot
*three* expressions on top of each other? I tried several
