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

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.

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.
Cheers,

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):

mathematical expression in varnames of lattice parallel plot
How can I insert mathematical expressions for variable names in a
lattice parallel plot? I tried to implement mathematical expressions in
varnames, however, without success.
For example, neither
parallel(~iris[1:4] | Species, iris,
varnames=c("P[Width]", "Petal[length]", "alpha[Width]", "Sepal[Length]"))
nor

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) &&

lattice: defining grouping variable only for the upper/lower panel with splom
Using the mtcars dataset, how to define the grouping variable to be valid
only for the upper or lower panel?
The following doesn't work:

data=mtcars, pscales=0,

upper.panel = function(...){

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:

saving sublist lda object with save.image()
Greetings R experts,
I'm having some difficulty recovering lda objects that I've saved within sublists using the save.image() function. I am running a script that exports a variety of different information as a list, included within that list is an lda object. I then take that list and create a list of that with all the different replications I've run. Unfortunately I've been

kernlab kpca predict
Hi!
The kernlab function kpca() mentions that new observations can be transformed by using predict. Theres also an example in the documentation, but as you can see i am getting an error there (As i do with my own data). I'm not sure whats wrong at the moment. I haven't any predict functions written by myself in the workspace either. I've tested it with using the matrix version and the

Is there a simpler method to achieve the following: When I obtain an

of NAs. Here's a dummy example:

unexpected behavior of trellis calls inside a user-defined function
I am making a battery of levelplots and wireframes for several fitted
models. I wrote a function that takes the fitted model object as the
sole argument and produces these plots. Various strange behavior
ensued, but I have identified one very concrete issue (illustrated
below): when my figure-drawing function includes the addition of
points/lines to trellis plots, some of the

multiple plots per page using hist and pdf
Hello,
I am puzzled by the behavior of hist() when generating multiple plots
per page on the pdf device. In the following example two pdf files
are generated. The first results in 4 plots on one pdf page as
expected. However, the second, which swaps one of the plot() calls
for hist(), results in a 4 page pdf with one plot per page.

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?
