Dear r-help list members, I'm experiencing problems getting type="b" (or "o" or "c") to work in llines(). Try, e.g., the following scaled-down example: x <- factor(c("a", "b", "a", "b")) y <- c(1,2,1,2) z <- factor(c("A", "A", "B", "B")) symbols <- 1:2 lines <- 1:2 colors <- 1:2 zvals <- levels(z)...

Another question about lattice: Is there a way to use plotmath in the labels and strips? E.g. xyplot(y~x|group,data=test.df, panel=function(x,y,subscripts,df) { llines(x,y,col="black",lwd=2) llines(x,df[subscripts,"lowerCI"],lty=2,col="#aaaaaa") llines(x,df[subscripts,"upperCI"],lty=2,col="#aaaaaa") }, strip=function(...) { # not sure what to put here # but I woul...

If I have a contourplot (in the lattice package) and I want to add straight lines to it, how do I do this? I see that there are llines() and lsegement() functions for lattice plots, but they don't seem to do anything in this case: library(lattice) library(KernSmooth) x=rnorm(10000) y=x+rnorm(x,0,.5) a=bkde2D(cbind(x,y),.7) z=as.vector(a$fhat) grid=expand.grid(x=a$x1,y=a$x2) grid$z=z contourplot(z~x*y,data=grid,region=T,col....

...0), 2), FF = factor(rep(letters[1:2], each = 20)) ) library(lattice) xyplot(RR ~ LL | FF, ds1, scales = list(x = list(log = TRUE)), aspect = "xy", subscripts = TRUE, ID = ds2$FF, panel = function(x, y, subscripts, ID, ...) { w <- unique(ds1$FF[subscripts]) llines(log10(ds2$LL[ID == w]), ds2$RR[ID == w], ...) panel.xyplot(x, y, ...) } ) Note that the x-variable of llines must be logged to plot the correct values and so the scales argument seems to apply only to the x, y arguments passed to the panel function. Thank you. best, Ken -- Ken Knobl...

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]]

...ifcfg-eth0? Note that a normal bootup into CentOS 4.1 outside of the Grub Xen bootup works fine since it''s sensing the mac address of the NIC in the machine rather than what I suspect is a virtualized mac address that Xen provides upon a Xen bootup. I''ve tried removing the HWADDR= lline in ifcfg-eth0 but that just makes the complaint different and eth0 won''t startup at all inside or outside of Xen. Is there someplace in the vif-bridge script to hardcode this required mac address to line it up with the ifcfg-eth0 HWADDR= mac address or is the place to hardcode a fixed mac...

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 helpeRs, I am attempting to read in a series of csv files so I can bind them into one large dataframe.

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

...~ x ) model.y <- g$coef[1]+g$coef[2]*x plot(x,y) # a plot of the data lines( x, model.y ) # a plot of the model, superimposed on the first plot With Lattice graphics I've got this far: library(lattice) plot1 <- xyplot(y ~ x) plot2 <- xyplot(model.y ~ x, panel = function(x, y) { llines(x=x, y=y) }) print(plot1, more=TRUE, position=c(0,0.5,1,1)) print(plot2, position=c(0,0,1,0.5)) But this just produces two graphs, one above the other. How do I overlay them? What should I be doing in order to get the same result as with the base graphics? Thank you for your thoughts, Matth...

...his you will see a datapoint and line extend into the pink area. However, if xyplot is used, it doesn't extend past its borders: xyplot(y~x, xlim=c(0,1), ylim=c(0,1), type=c("p","l")) From what I understand so far: xyplot calls panel.xyplot panel.xyplot calls lpoints and llines neither lpoints nor llines do much except call xy.coords and then call lplot.xy lplot.xy calls grid.points and grid.lines Where in this code does the clipping occur? I'm quite baffled really. Thank you for considering this, Matthew

I would like to use llines() to draw lines with square endings in lattice plots. But the default behavior seems to be to draw lines with round endings. How can I change this? I'm looking for a parameter like par('lend') or get.gpar('lineend'), but trellis.par.get() doesn't seem to have anythi...

...the Hmisc package, I tried to create an xYplot (single panel only) and was confused to find that I could not add anything else to the plot (abline, lines, etc.). Thankfully, [1] points out panel functions. This works as expected for panel.abline, but as soon as I'm using panel.lines (or llines or lpoints) from the "lattice" package (version 0.17-17 with R 2.8.1), it seems that it is not using the coordinate system that the original plot used, i.e. the graph does not work at all. My code: pfunc <- function(x,y,...) { panel.xYplot(x, y, ...) panel.abline(h=4.0, c...

R folks, I can't seem to find the instructions in the help files for the lattice package that explain how to add lines, such as with lines() or ?, to a levelplot. I'd be grateful if someone could point me in the proper direction. Cheers, Jeff ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Jeff Jorgensen Center for Limnology jcjorgensen at wisc.edu

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

Hi, I would know how to plot two variograms on a same graph. I can plot one by one but I would draw both on the same one. Is it possible? Do i need any special package? Thanks! Cordialement Damien Landais
