Hi, The solution to my problem is to use 'lsegments' instead of 'segments' within lattice commands. (Although I wont forget again, a comment in the segments help file referring to 'lsegments' might help others not to make the same mistake in the future.) My thanks to Renaud Lancelot. Regards, John.

Dear R-Users, how to include error bars within lattice? How should the panel = function(x,y,...){ looks like? Does panel.arrows works here as well? I appreciate any help on this. Regards, Mario AT [[alternative HTML version deleted]]

First, apologies for no example data but I don't think it's needed in this case, Q: Can (and if so how ) the line end style be changed for 'cloud' plots? I've tried par(lend=2), trellis.par.set(add.line = list(lend=2)) and much googling but to no avail Thanks in advance Dan P.S. the reason for this is that the round end looks bad at lwd=3 or more Daniel Alcock Malaria

Dear R-helpers, I have a function that adds some segments to the current plot, but if I the current plot is made with any of the lattice functions (in my case, levelplot), I should use lsegments rather than segments. How can I tell if the current device was made with plot() or e.g. levelplot() or another lattice function? dev.cur() does not help me, it just tells me "windows 2". (Windows XP). thanks Remko ------------------------------------------------- Remko Duursma Post-D...

Hi all, I have been previously been using scatterplot3d package to create some graphs but unfortunately it does not allow me to rotate the plot on all three axis. The cloud() function in the lattice package does allow me to do so. When I was using scatterplot3d I was using a script (Shown Below) to calculate the mean, quartiles and range limits for all three axis and I was representing that on the

Dear r-help, I need to draw xyplot() graphs with several regression lines: one line for the whole range of x (the variable on the horizontal axis) and two additional lines for subranges of x. Is it possible to make first regression line (panel.lmline(x,y,...);) to be drawn on the whole graph and regression lines of the subsets to be drawn only over their subsets? I have defined

I suspect that I misunderstand the coordinate system that lattice uses for contour plots. Can anyone enlighte...

In the example: x = rep(c(0,0,1,1),4) y = rep(c(0,1,0,1),4) z = c(1,0,1,0,0,0,1,1,0,1,0,0,1,1,1,1) f = as.factor(c(rep("a",4),rep("b",4),rep("c",4),rep("d",4))) levelplot(z~x+y|f,data.frame(x=x,y=y,z=z,f=f)) I noted that the last ("d") plot remains empty. I guess the reason for this is that the values are constant (1), but I consider it more

Dear R list members, I'd like to produce rug plots at the bottom of panels in a trellis display (using the lattice package), but par("usr") doesn't return user coordinates for panels, and consequently rug fails, as the following example (suggested to me by Georges Monette) illustrates: > x <- rnorm(50) > y <- rnorm(50) > f <-

I'm looking for a way to plot lines on top of a levelplot(), where the lines are borders between cells of different values. The clines() function provides contours suitable for continuous data. I am dealing with discrete values, spatial clusters of nodes where each cluster has an integer value, and I want to plot the borderlines between these areas. So, in a levelplot having nodes with

Hi, I use panel.points to add points to a xyplot graphic. But I like to use the sunflowerplot to plot my points because this is very superimposed. It is possible to use this? I try but it dont work directly. It may be need to put this function inside a panel.??? Thanks Ronaldo -- Where there's a will, there's a relative. -- > Prof. Ronaldo Reis J?nior | .''`.
