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...

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,...

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 a...

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

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 som...

...o 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 red? More generally, how can I provide a matrix of colors to be used by splom() such that all data points in the corresponding sub-plot of the scatter plot matrix are shown in the specified color? Cheers, Marius Here is the code: library(lattice) entrymat=matrix(0,nrow=3,ncol=3) entrymat[1,2]="black" entrymat[1,3]="blue" entrymat[2,3]="red"...

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, colu...

...lty = 2) circ2 <- ellipse(diag(rep(1, 2)), t = 2) panel.xyplot(circ2[,1], circ2[,2], type = "l", lty = 2) panel.xyplot(x, y) } xyplot(X2 ~ X1, data = dat, panel = panel.circ, aspect = 1) I'd like to to the sample with splom, but with groups. My latest attempt: panel.circ2 <- function(x, y, groups, ...) { circ1 <- ellipse(diag(rep(1, 2)), t = 1) panel.xyplot(circ1[,1], circ1[,2], type = "l", lty = 2) circ2 <- ellipse(diag(rep(1, 2)), t = 2) panel....

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! xcui

...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 reproducible example: ##### require(lattice) temp.df <- sapply(1:30, function(i) rnorm(20, 0,1)) splom(~temp.df, aspect="fill", varnames=paste("coord", 1:30, sep=""), xlab="", pscales=0, varname.cex=0.6, panel=function(x, y, ...){ panel.xyplot(x,y, cex=0.2, xlab="", ylab="") }) splom(~matrix(c(1,2,3), nc=3), aspect="fill", va...

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. Here is my...

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(&quot...

All, I was having trouble trying to create a new class of data and pass it on to splom (in the lattice library). I mentioned this to Martin Morgan after a talk he gave. Following is not so much a question, but rather an answer from Morgan that might be useful to others. Here is the edited part of an email conversation with him: On Thursday, August 26, 2010 1:36 PM, Martin Mor...

But I dont'know how to change panel.pairs inside superpanel in order to use my panel.line1 and panel.cor1 functions. ------------------------------------------------------------------------ splom(~temp.df, aspect="fill", varnames=paste("coord", 1:10, sep=""),...

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) &...

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) onto the corresponding panels from (1). (By the way, the data used for the regressions are not quite the same...

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, Ma...

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 w...

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 this message in context: http://r.789695.n4.nabble.com/lattice-d...

Context: Windows XP, R 1.8.1 I'm studying Venables-Ripley "MASS" book and having a go at the many examples in library MASS. The code I'm checking (from script ch04.R) now is ...... data(swiss) splom(~ swiss, aspect = "fill", panel = function(x, y, ...) { panel.xyplot(x, y, ...); panel.loess(x, y, ...) } ) which produces an agreable plot with a gray background and cyan points, but..... Copying the plot as a metafile into Word and having a laser printer I'd better stick t...
