similar to: specifying a key for a trellis display

Dear expeRts, I am not sure if I found a bug... I would like to create a function that itself creates a lattice plot without colors. Following http://www.mail-archive.com/r-help at r-project.org/msg64699.html I use trellis.device() to set the colors to FALSE. Whenever I call the minimal example below *with* trellis.device(), Quartz opens a window (I am working on a MAC), which it shouldn't,

Dear all I have two questions regarding trellis plots - which I hope you may be able to help me with. Is it possible to place the key in a trellis plot on the panel (instead of beside the panel)? This will cause the same key to be reproduced on each panel. Please see the plot below - here I placed the legend below the plot. I tried moving the key to the function statement, but it did not really

Hi: (Tried to find a bug report about this issue, but was unable to find it, let me know if this is a known issue) I have been working on an interface to highlight xyplot panels on mouse overs in JavaGD but I have stumbled with what seems to be a bug in trellis.focus. I am using R 2.8 with lattice 0.17-15 *** To replicate the bug: 1.- display an xyplot. For example, from the xyplot help page:

Folks: I would like to write two lines of text in two different font sizes (or faces or ...) as the title ("main") of a trellis plot. The following code does it, but not well: xyplot((0:1)~(0:1), main = textGrob(lab=c("Some Text","Some More Text"),y=c(.95,.8), gp=gpar(cex=c(1.2,1.0))) ) There is too much space between the title text and the plot. I assume

Dear R users, I have a lot of experience with traditional R graphics, but I decided to turn to trellis as it was recommended for spatial graphs by the sp package. In traditional R graphics I always first set the size of the device region absolute units (e.g. mm) and then I firmly fix the inner margins with mai and the outer margins with oma also in absolute units. What is left from the device

I've just upgraded to 2.0.1 and was taken by surprise by the changes in graphical parameter handling for lattice plots. I'd previously been using 1.9.1. The old settings seem to have been replaced by a daunting number of new options. I've poked around a bit and have not seen any discussion of the changes in the newsletter or on r-help but maybe I'm overlooking something?

Dear all I have a problem when I make a trellis plot - I would like to reduce the white margin surrounding the plot. I used S some years age, as I remember it was possible to use the "par" and "oma" to control margin size even on a trelllis plot (see the plot below). However, it does not seem to work in R. All suggestions will be highly appreciated. Br Henrik

I've been using the following code to plot using Sweave in version 1.9.1 library(RODBC) library(lattice) channel <-odbcConnectExcel("h:/water.xls") data <- sqlQuery(channel,"select * from `Sheet1$` where Test = 'TOC' and (Valve='5010-05' or Valve='8030-V26' or Valve='1180-08' or Valve='5040-08')") odbcClose(channel) srt <-

Is there an equivalent way to set plotting parameters as in par(mai=c(......)) in the Lattice package? I searched trellis.par.get(), but am not sure which one can be used. Paul E. Green [[alternative HTML version deleted]]

Dear all, After going through the Lattice doc and R-help list and google, I got the feeling that there is no function in lattice or other package to compute a pie chart object of class "trellis". Although pie charts are obviously not considered optimal even in the pie() doc ;-) , pie chart trellis objects would be easy positioned e.g. over a map drawn with the grids package. Can

Suppose that (e.g.) xyplot() returns an object "xxx" with (say) 3 pages. I would like to extract/plot (print) just one of these pages, e.g. page 2. Here's a toy example: x <- rep(seq(0,1,length=11),12) set.seed(42) y <- rnorm(3*44) a <- rep(letters[1:12],each=11) dta <- data.frame(x=x,y=y,a=a) xxx <- xyplot(y~x|a,data=dta,layout=c(2,2)) I would to extract from

Hi all -- I'm using trellis to generate bar charts, but there's no built-in function to generate error bars or confidence intervals, as far as I can tell. I assumed I could just write my own panel function to add them, so I searched the archive, and found a posting from the author of the package stating "... placing multiple bars side by side needs specialized calculations, which

Hello, I would like to create a sequence of plots (using a for loop). I read in the FAQ that print() has to be used in order to obtain any output. This works perfectly fine as long as I only consider one function call in the loop, but I would like to add mtext() to the each plot in the loop. Unfortunately, this did not work. Any suggestions? As you can see from the provided example,

Dear All, I am hoping to implement a barchart using trellis graphics where all elements have a line width of 2. Using trellis.par.set(), I am able to make most elements lwd=2, but not all. In particular, the top of the box (above the upper most strip) and the left y-axis remain one point. Code with a barchart() example is below. Any advice would be greatly appreciated. Thanks for your

This is a question relating to the Trellis function in R. I have a set of socioeconomic data that I would like to display with the xyplot() function for several states. I will have a total of 6 plots, with the y-variable as "Age Group", and the x-variable as "Median Income". Suitability of the plots aside (this cannot be changed), I need to plot the points of one of the states

Hello, I would like to display two groups of dots in different colors or style and additionnaly a linear regression for all the dots in panel plots of a Trellis graph. Actually to get in each panel the equivalent of: plot(x[mois==3],y[mois==3],col="blue") points(x[mois==9],y[mois==9],col="red") abline(lm(y~x), col="green") "mois" being a grouping

Hi, I have a the code for a plot that works perfectly running in R and printing to a Quartz object but which doesn't work when I make the trellis device a pdf. The code is as follows: ---- trellis.device(device="pdf", new=TRUE) trellis.par.set(my.theme()) dotplot(Y ~ X | C, groups=G, data=D, layout=c(2,1), ... ) trellis.focus("panel", 1, 1) for (y in 1:5) {

Hi all, I've got some problems when changing the trellis settings for the lattice plots. The plots look exactly as I want them to when calling show.settings() as well as when plotting them in the graphical window. But when printing to a pdf file, none of the settings are used!? Does anyone know what might have happened? Because the when changing the trellis settings, these should remain in

Hello, I am trying to write a new "top level" Trellis/lattice function. By "top-level", I mean a function like 'xyplot', 'histogram', 'bwplot', etc. These functions all call 'trellis.skeleton', which I am unable to call; an attempt to invoke the function that does so yields the error message: ----- Error in do.call("trellis.skeleton",

Hello. First: R 2.3.1 on Windows XP. I am trying to add information (sample size) to the Trellis strips which I am successful using the trellis.focus function with the default Windows device. However, I typically use the postscript device as I use LaTeX and \includegraphic for incorporating graphs into stat reviews. Here's some example code (apologies for the lack of creativity and
