Adding axis lines to splom plots
Hi,
I am trying to produce a 30x30 lattice grid. The 30 variables naturally
fall into three groups of ten and I would like to add thicker axis lines
around these to highlight this. However, I can only do this separately,
so far, and I don't know how to superimpose the grid with the thicker
lines (separating the 10x10 groups) onto the overall grid of all 30x30
plots. I enclose a

How to put given values in lower triangle of splom-plot?
Dear R-experts,
I have found a splom-modification online which is given below. This
works perfectly, but I would like to have a matrix of given
correlation values to be used in the lower triangular part
(lower.panel) of the splom-plot instead of calculated correlation
values. Here is the matrix I would like to use (it can be any other
convenient data structure):

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

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?

How to use expression(italic()) in a "vectorized" way (within a function)?
Dear expeRts,
I would like to use expression() for creating labels in a splom, as shown in the
first minimal example below. Is there any way I can simplify having to write
"expression(italic(...))" several times?
The second example is what I tried so far, but I can't manage to get italic() to
work. Moreover, it still seems bulky...
Cheers,
Marius

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

circular reference lines in splom
Hello everyone,
I'm stumped. I'd like to create a scatterplot matrix with circular

Splom custom superpanels
I thought one nice addition to a splom figure would be to have the
scatterplots in the upper triangle and a color-coordinated
correlation matrix on the bottom. So I tried my hand at customizing
panel.pairs(), and was rebuffed. Many times. Four hours of
fruitless debugging later, I turn to you for help:

accessing column and row numbers inside splom in lattice
Hi,
When using splom() in the lattice package, I would like to be able to
access the row and column number of each individual pairs plot ,
similar to the way that current.row() and current.column() can be used
in other lattice plotting functions such as xyplot. For example, I
would like to be able to write something along the lines of
library(mvtnorm)

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.

lattice splom: how to adjust space between tick marks and tick labels?
Dear expeRts,
how can I decrease the space between the tick marks and the corresponding labels in an splom?
See here:
library(lattice)
U <- matrix(runif(4000), ncol = 8)
splom(U, axis.text.cex = 0.2) # => space between the [small] tick labels and tick marks is/seems to be too large
I checked ?panel.pairs but could not find an option for that.

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.

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:

= panel.superpose, col=colors)
}
and then call it like in

splom Tick Location
When using the 'splom' function of the 'lattice' packge, is it possible to
get all the tick marks in the outer margins of the plot?
X <- as.data.frame(matrix(rnorm(1000), 100, 10))
plot(X) ## Tick marks are in the outer margin
splom(X) ## Tick marks are inside the on-diagonal panels
Thanks.

can not produce graph using "splom"
Hi,
I wrote a function basically to first read an input data file, then open an pdf file and draw graph using "splom". When testing, I ran the function line by line, it can produce nice plot, but with like 50 warnings. However, whenever I ran this function as a whole, it can not produce any plot, the pdf file has nothing in it. It seems the "splom" function even hasn't

change axis labels and text size in "splom"
Hi everyone:
I'm using "splom" to draw scatterplot matrix. I'm wondering how can I change the axis labels to c(1,10,100,1000,...)
instead of c(1,2,3,...), and also how can I change the text size (for labels)?
Thanks a lot!
