If you send a better readable message with really reproducible code, we
may provide a solution, this way it is really hard to read your code.
And yes, please do not send html mail. My guess is that par(new=TRUE)
will help, but I do not want to construct the examples at first.

Dear Madame or Sir,I am having a problem in combining density-smoothed scatterplot matrices with a plot of kernel destiny
estimations of each dimension plotted on the respective field of the diagonal.I have tried following approach using the
package "sm" for the kernel density estimation, as well as "MASS" respectively:pairs(myTable[,
1:4],panel=function(x,y, ...){ xy=kde2d(x,y) image(xy, add=TRUE)},diag.panel = function(x,...){plot(density(x), add
= TRUE)#boxplot(x, add = TRUE)})where myTable is an ordinary table I am using the first four columns of. Unfortunately this
produces an error stating that plot has created a new plot. I suppose this is the same situation when forgetting "add
= TRUE" with plotting functions such as boxplot (as in my code used with "boxplot(x, add = TRUE)" ) or any
other (e.g. smoothScatter). Analyzing the partial plot, which can be seen before R rejects my code, I come to the
conclusion that add might not be a valid argument for "plot
". My questions therefore is, whether there is an option to plot the result of the 1d
kernel density estimation to the diagonal of the scatterplot produced by pairs or which plot
function is valid in this case. So basically I would like to generate the same output I am
able to produce with boxplots on the diagonal with a density estimation.Additional question: I
bet there is an opportunity to include both the boxplot and the kernel density estimation on
each field of the diagonal (as I saw before in a published paper), but I just could not figure
out how to "overdraw". Maybe you could give me a slight idea (reference would be
fine, too) on how to achieve this. I would be highly thankful!Kind regards and many thanks in
advance,-Patrick Grossman --
