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 reason

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) library(lattice) y <-

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):

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: panel.pairs(z=teststatfull[,6:12], pscales=0, panel.subscripts=FALSE, subscripts=,

Hi, The following code produces a plot on X11: splom(~iris[1:4], groups = Species, data = iris, panel = panel.superpose, key = list(title = "Three Varieties of Iris", columns = 3, points = list(pch = super.sym$pch[1:3], col = super.sym$col[1:3]), text = list(c("Setosa", "Versicolor", "Virginica")))) However,

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: > library(lattice) > splom(~iris[1:4], groups = Species, data = iris,

trellis.device(bg="white", color=F) before your call to splom could make what you want but take also a look at ?trellis.par.set Stefano > -----Messaggio originale----- > Da: v.demartino2 at virgilio.it [mailto:v.demartino2 at virgilio.it] > Inviato: mercoled? 3 marzo 2004 12.10 > A: r-help > Oggetto: [R] Changing background in splom et al. > > > Context:

Hello, I have a customized pairs () fonction as follows that displays correctely my data. ------------------------------------------------------------------------ panel.cor1 <- function (x, y, digits=2, prefix="") { usr <- par("usr"); on.exit(par(usr)) par(usr = c(0, 1, 0, 1)) r <- cor(x, y,use="pairwise.complete.obs",

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

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 (I've commented the

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

All, I have long variable names that are being fed through splom (R 1.8.1). I'd like to resize the text printed on the diagonals to better display the names (unless anyone can suggest another approach - creative use of varnames). I've looked at the code, R-Help, ?splom and the Trellis User's Guide to no avail. Any suggestions? Thanks in advance, Max Kuhn, Ph.D. Becton Dickinson

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: # Code start splom(~data.frame(mpg, disp, hp, drat, wt, qsec), data=mtcars, pscales=0, auto.key=list(columns=3), upper.panel = function(...){ panel.grid(...) panel.xyplot(groups=cyl,...) } ) # Code end -- View

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. - Elliot [[alternative HTML version deleted]]

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

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: splom(~ log10(splomData[2:3]), groups = programs, data = splomData, panel = panel.superpose, key = list(title = paste(splomLoop,"Programs of Hog Analysis (Sorted by LR(GB))"), panel = panel.superpose, columns =

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? splom(szw[, n], pscales = 0, diag.panel

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) &&

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, Marius

Hello everyone, I'm stumped. I'd like to create a scatterplot matrix with circular reference lines. Here is an example in 2d: library(ellipse) set.seed(1) dat <- matrix(rnorm(300), ncol = 3) colnames(dat) <- c("X1", "X2", "X3") dat <- as.data.frame(dat) grps <- factor(rep(letters[1:4], 25)) panel.circ <- function(x, y, ...) { circ1
