similar to: "pairs" with same xlim and ylim scale

Hello, I'm trying to pull off a certain graph using splom, and can't quite get my panel functions right. Basically, the equivalent using pairs would be something like this (using iris data set as an example): panel.corval <- function(x, y, digits=2, prefix="", cex.cor,col,pch) { usr <- par("usr"); on.exit(par(usr)) par(usr = c(0, 1, 0, 1))

Hello, I'd like to add custom labels to my pair() plot. These labels include math expression but they aren't correctly displayed... Further, I want that the boxes for the text.panel (diagonal) have an other background color (grey80). Is that generally possible? If yes how do I have to set it? What I've so far is: panel.cor <- function(x, y, digits=2, prefix="",

Hi there, I am just starting in R and this might be a very basic question. I applied one on the examples of pairs() to my own data. The examples shows scatter plots on one side of the matrix and the correlation coefficients on the other which works well. I then modified it slightly because I want different colors in the plots. Now i am getting the error of unused arguments, because the color

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",

Hi, I am just starting to use R for a graduate course, and I like how the correlation matrix at http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=137 I did something similar by copying from the examples(pairs), but it seems that I need to jitter the bottom panel... and I have no idea how to do that, and I mean no idea at all. I'd appreciate any help... Here are the graphs:

Hi, First of all, thanks for the efforts of all the developers and contributors - I'm very new to R and at the moment am just using it to create some graphics, but it seems to be quite powerful. I've googled the archives and wasn't able to find anyhting that dealt with this problem, so would appreciate any suggestions/tips. In a pairs plot I'd like to plot a linear regression line

Greetings R users, I am an R graphics newbie trying to produce a custom trellis plot using pairs() with R 2.7.2. I have spatial data on which I run a geographically weighted regression (gwr, using the -spgwr- package). I want to check the gwr coefficients for multicollinearity and spatial association, following Wheeler and Tiefelsdorf (2005), and I would like to summarize the results of this

Hi list. I was saving my modified pairs graphic using a custom panel from the R Graphics site, and I got an interesting difference in the final image when I save it as eps or png. This custom panel make possible to show at the left side of the pairs plot the p-value as symbol and the correlation r value with its cex proportional to the r value itself. Well, when saving as a png file

Has anyone successfully created a PNG file for a dendrogram? I am able to successfully launch and view a dendrogram in Quartz. However, the dendrogram is quite large (too large to read on a computer screen), so I am trying to save it to a file (1000x4000 pixels) for viewing in other apps. However, whenever I try to initiate a PNG device, I get a "need finitite 'xlim' values"

Hi, I am trying to do plot a scatterplot matrix using pairs() from the package graphics. There are now a few things I'd like to improve for a better understanding. 1) My scatterplot uses two log-scaled axis...as I don't know how to set them in pairs() I calculated the log before but now the labels are not as I want them. I'd like them as 10^1,10^2 etc. What is the best way to handle

Hi, I have the following problem. I wanted to get a matrix of scatterplots and I used pairs. I wanted to add the line y=x in each plot and I created a panel function for this scope. I used points and abline in the following way: ## put y=x in each plot panel.lin<- function(x, y) { points(x,y, pch=21, bg=par("bg"), col = "black",cex=2)

(I have checked the 2000 &2001 archives) Awhile ago, someone posted a function to plot a scatterplot matrix with the upper triangle containing plots (and maybe fitted curves?) and the lower triangle containing the correlation coefs. I have lost that code and would love it again if anyone has it. Thanks, Henry ***************************** Martin Henry H. Stevens HStevens at muohio.edu tel:

Hi there, I got a piece of code for the Iris data which allows to display correlation coefficients for each Iris species in the lower panel (color coded). I would now like to add e.g. a "*" to show the significance of each correlation next to the correlation coefficient. Furthermore I would like to make a t.test between the species "setosa" and "versicolor" for

my data are matrix with 3 numeric columns. would like to have pairs plot with scatterplots in the upper with hist at the diag and with correlation at the lower. actually default pairs does almost what I want but looks semi awesome. Especially, i didn't find out how to remove the axes from the lower part where I do only want to display the numeric values correlations there and somehow axes

Hi, I have a problem to define the range of x and y axis in pairs() for my scatterplots. In low-level plots I can specify that by providing xlim and ylim. This also works for pairs() even if warnings tell me that it doesn't (see below). But if I add upper.panel and/or lower.panel it doesn't work - I get an error message saying that there's an error in "upper.panel

Hi List, I would appreciate any suggestion on how can I make a text I’ve inserted in a plot show some contrast? With this I mean that I have a white text on a plot and I would like to make a tiny border around it in black, so even being small sized and the entire graphic being small in the text page I’ll insert it. It will be visible. Well I tried inserting a box() function inside the text()

Full_Name: Clay B Version: 2.5.0 (2007-04-23) OS: Solaris Nevada Build 55b Submission from: (NULL) (65.101.229.198) I find that running this script causes R to segfault reliably. However, running just for one system at a time (modifying the for loop updating iter to run just for a system at a time works). The system is a Sun W2100z with 12 GB of ram, and R segfaults using only around 360 MB of

Hi everyone, I'm trying to calculate correlation coefficients between corresponding columns in two matrices with identical dimensions but different data. The problem is that the matrices contain NAs in different locations. I am using the following code to try to calculate correlations between complete sets of data: #Code start maxcol<-ncol(mat1) for (i in 1:maxcol) {

Hi all, I'm running a monte carlo test of a neural network tool I've developed, and it looks like it's going to take a very long time if I run it in R so I'm interested in translating my code (included below) into something faster like Fortran (which I'll have to learn from scratch). However, as you'll see my code loads the nnet library and uses it quite a bit, and I

Dear List-mates, I have been trying to set up a 4x8 trellis plot (that is, 4 columns, 8 rows), and would like to have the axis limits set based on the data range of rows (for ylim) and columns (for xlim). I've been using the call: foo<-xyplot(y~x|Epoch+Subject, type=c("l","r"), par.strip.text=list(cex=0.5), ...) and updating to see different effects of scale
