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) &&

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

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=,

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

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",

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

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 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

This is extremely annoying (and it smells of rat). As of this time (1013 am ET), Google issues the following nasty warning: "This site may harm your computer" when I try to visit any of the CRAN package repository sites or CRAN task view. The funny thing is that Google's Safe Browsing Diagnostic page (it gives diagnostics about any page that it may contain Malware) does not seem

Hi, You may want to try the double exponential transformation on the numerator and the denominator on this one. The method is described in detail here: http://projecteuclid.org/DPubS?service=UI&version=1.0&verb=Display&handle=euclid.prims/1145474600 If you want to give it a shot outside R there are a couple of C/C++ implementations out there:

Hi, I noticed whether some one could explain why "&" and "&&" behave differently in data frame transformations. Consider the following : a<-data.frame(r=c(0,0,2,3),g=c(0,2,0,2.1)) Then: > transform(a,R=ifelse(r>0 && g> 0,log(r/g),NA)) r g R 1 0 0.0 NA 2 0 2.0 NA 3 2 0.0 NA 4 3 2.1 NA but > transform(a,R=ifelse(r>0 & g>

Hi all, I would like to strip the R prompt from a series of code lines and copy the resulting text into a R script. For example, consider the following : ##### str1<-" > library(MASS) > data(Cars93) > attach(Cars93) > imosaic(data.frame(AirBags,Cylinders,Origin))" str2<-gsub('>','',str1) ###### This gives, as expected .? > str2 [1] "\n

I just (finally!!!) got R version 1.8.1 to configure and build under Solaris 9 (after much travail; there were funnies in my environment variables that mucked things up, but that's another story). Anyhow, when I ran ``make check'' I got an error right toward the end. Looking in the directory ``tests'' I found that the error was associated with the file reg-tests-3.R, and the

Dear Deepayan Sarkar, I have (again) a question concerning "panel" and my function "SplomT", see attachments. Some time ago you helped me to write this function, thanks again. I have used it to great advantage in my statistics instructions. Now the problem I encounter is that the .pdf figure generated in Sweave consists of one extra empty page at the start. This prevents

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 Morgan wrote:

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 <-

dum is a simple data frame transferred to Splus using the dump() command in Splus and the source() in R. All fields are numeric. There are no missing data. The data frame looks like it is should: > apply(dum,2,mode) yrcl sland s02 s234 "numeric" "numeric" "numeric" "numeric" > apply(dum,2,is.vector) yrcl sland s02 s234
