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 g...

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 d...

...'m just starting to work with lattice graphics, and am having difficulty understanding how to control various graphic parameters (font sizes, etc.). [I'm actually using xyplot via plot.effect() in the car package, and would like to be able to set some global defaults.] I read ?xyplot and ?trellis.par.set-- which contains no complete list of parameters, just a reference to print(trellis.par.get()) > print(trellis.par.get()) $fontsize $fontsize$default [1] 10 I tried > trellis.par.set("fontsize", 12) > data(quakes) > Depth <- equal.count(quakes$depth, number=8...

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 trel...

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 resem...

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) { panel.segments(...) } trellis.unfocus() trellis.focus("...

Hi, I'm recently working on a multipage bwplot() using the lattice package. In this context I was trying to use the panel.abline() function individually on certain panels but not all. After some research I found the trellis.focus() and trellis.unfocus() functions which enabled me to do something like: trellis.focus("panel", 1, 3) do.call("panel.abline", list (c(0.5, 0), col="tomato", lty=2 )) trellis.unfocus() The result is quite what I expected and working properly as...

Dear R-users, I am trying to produce trellis (png, or jpeg) graphs with transparent background, but I cannot manage to make that happen. I tried to play around with themes but to no avail. Any advise on the following example will be greatly appreciated: Thank you Sebastien #### library(lattice) df <- data.frame(a=rep(1:4,4), b=rep(1:4,...

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, since I only want to create the plot, but do not intend to "print" it. Moreover, if I check the value of b, it pri...

...itted models. I wrote a function that takes the fitted model object as the sole argument and produces these plots. Various strange behavior ensued, but I have identified one very concrete issue (illustrated below): when my figure-drawing function includes the addition of points/lines to trellis plots, some of the information (main title, placement of additional points) from my i-th function call is leaking over into the i+1-th call. In the example below, I just get unexpected results. In my actual application, it breaks the whole function and one of the error messages I've g...

Dear All: I need draw some figure through trellis.device and save them as pdf files. How can I close trellis.device (something like dev.off() in nonlattice figure)? Many thanks Zhongming Yang --------------------------------- [[alternative HTML version deleted]]

Dear R-users, I have written the following code to generate some trellis plots. It works perfectly fine except that it is quite slow when it is apply to my typical datasets (over several thousands of lines). I believe the problem comes from the loops I am using to subset my data.frame. I read in the archives that the tapply function is often more efficient than a l...

Hi I'm trying to print several plots to a multi-page postscript file. Some plots are output of basic commands, some are produced by "trellis" commands (from the package lattice). Right now I'm not able to get a straightforward black and white color scheme for the latter kind: when I open the postscript file the "trellis" plots are invisible, or parts of them are (usually the bounding box/axes/axes marks). Here is...
