similar to: Add a legend to a pairs plot??

I have a bivariate plot of axis2 against axis1 (data below). I would like to use different size, type and color for points in the plot for the point coming from different region. For some reasons, I cannot get it done. Below is my code. col <- rep(c("blue", "red", "darkgreen"), c(16, 16, 16)) ## Choose different size of points cex <- rep(c(1, 1.2, 1), c(16, 16,

All, Does anyone know if there is an option I can set to turn screen-buffered output on and off with the win32 rgui? (Apart from the point and click method). I am running some simulations where it is useful to watch output but it gets mildly tiresome having to manually switch things on and off via the gui. Thanks Toby. > version _ platform i386-pc-mingw32 arch

Hi, Is it possible to create a legend in a pairs() plot? For example, suppose I have the following R codes: data(iris) pairs(iris[1:4], main = "Anderson's Iris Data -- 3 species", pch = 21, bg = c("red", "green3", "blue")[codes(iris$Species)]) How can I created a legend that shows which colour represents to which Iris species? Thanks,

Is there a way to put a legend on an xyplot -- eg, something akin to the key function? Or, is there a way to get the R legend function to work on a lattice plot? To the people who have done the work on lattice and grid: Thanks for making lattice. I'm finding it very useful. Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E.

I am trying to create a plot that has multiple plot characters for each point (e.g. a point within a triangle, a triangle within a square, etc). The workaround I have found to do this is by plotting twice, as in this example: x <- c(1.1, 2.3, 4.6) y <- c(2.0, 1.6, 3.2) plot(x, y) points(x,y, pch=20, col="red", cex=0.5) This works, but perhaps there is a better way to do it in one

Hi all, I'm having trouble connecting to an oracle database using RODBC under winXP. Unfortunately I can't really send a reproducable error as the initial call to odbcConnect seems to hangs R and I have to kill the session. I have been using RODBC to sucessfully connect to an MS Access DB that has tables linked through to the oracle database in question and that seems to work OK but it

Full_Name: Toby Patterson Version: 1.6.0 OS: winXP Submission from: (NULL) (140.79.2.3) I seem to be able to cause a predictable crash (i.e. the application terminates abnormally) in R using the library lattice. If I have x<-cbind(1:10,c(rep(1,7),rep(2,3)),rnorm(10)) library(lattice) xyplot(x[,1]~x[,3]|x[,2]) # works oK but reversing the ylim entries i.e.

All, When I try and compile a shared library (on WinXP) I get the following error: E:\data\proj>R CMD SHLIB toy_dll.c Makevars:1: *** missing separator. Stop. Has someone else had this error and fixed it? This code compiles and works fine on Linux (fedora core 2). Everything was working fine under R1.8.1 but I've broken something when I upgraded to R1.9.1. So I am assuming

All, I was wondering if someone had come across the problem of producing partial regression plots for glm objects in R? When using Splus in the past I have passed glm objects to the plot.gam function. To my knowledge this functionality isn't included in R ( I would be happily corrected here) and if someone had some code floating around to do this it would save me re-inventing wheels etc.

Hi, I am trying to use function pairs to plot the scatterplot, but I only want to keep the upper triangle, what's the argument to do this? Thanks, -Jack [[alternative HTML version deleted]]

I would like to add a legend to a pairs plot. Is there a simple way to do this? Just doing legend(.....) doesn't seem to get it. Thanks, Sean

Hi all (and particularly Deepayan), A while back Deepayan helped me with the query in the text below (thanks again). Specifically it was about changing the way that dates plotted on the axes of lattice plots. While this works using xyplot, everything comes apart when I use levelplot. The axis labels on the date axis are shown as the integer representation of the date (number of seconds since

Hi, I've looked at the parameters available for the legend function and cannot find a way to change the distance between the top of the box surrounding a legend and the legend's title. I have a math expression that raises the height of my title. If you don't mind the non-sensical title I give to the legend for this plot (Figure 3.20 in R Graphics): with(iris,

Dear R-users, I would like to add a legend at the bottom of pairs plots (it's my first use of this function). With the plot function, I usually add some additional space at the bottom when I define the size of the graphical device (using mar); grid functions then allows me to draw my legend as I want. Unfortunatley, this technique does not seem to work with the pairs function as the

Does the "legend" command work in the windows version of R? Here is the command that I'm using: legend(1,1,legend=c("G1","G2","G3","G4","G5","G6"),pch=array(1:6,dim=c (1,6))) When I use this on my existing graph in a window I get a solid black box at the lower left. If I use this with the postscript driver my output

(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:

I am making final adjustments to a multi-plot figure using basic and lattice. In the lattice plot, I would like to include a legend that matches the format of the legends in the other plots, which consist of appropriately colored squares (pch 22) followed by text. In lattice, I was able to get a legend using auto.key = list(x = .6, y = .6, corner = c(0, 0), pch=22) but my request for pch=22 was

Dear R Users! I've want to save a lattice "parallel" plot with legend as png: Plotting with legend works well, but when trying to save the plot there occurs a problem with the legend. ################################################### require(lattice) #Some data: data<-matrix(rnorm(100),ncol=5) #Plot works parallel(data)

Hi all, I am writing some C code where I want to use the findInterval function documented in "Writing R extensions/Utility functions". i.e. the C-version not the R version. It all compiles but the shared library is causing seg-faults and I'm obviously stuffing something up. Has anyone got any examples of calling this function they'd be will to share? I've searched through

All, I have some data of animal movements that I'm plotting using xyplot() from lattice. I want to have the date (class POSIXct object) on the Y-axis and the animals longitude on X-axis. Eg. xyplot(date ~ longitude, groups = animal, data = my.data) with data like: animal ptt year month day lon date 125 03P0014 13273 2003 7 10 150.38 2003-07-10 14:03:48 126
