Dear all, How can I make an index plot with lattice, that is plotting a vector simply against its particular index in the vector, i.e. something similar to y <- rnorm(10) plot(y) I don't want to specify the x's manually, as this could become cumbersome when having multiple panels. I tried something like library(lattice) mp <- function(x, y, ...) { x <- 1:length(y)

Hi, I need a custom axis function for a plot, but it seems that current.panel.limits() sometimes returns NaN limits for the plot, which it much harder to calculate anything sensible. An illustration: Given this axis function: vs.axis <- function(...){ xlim <- current.panel.limits()$xlim ylim <- current.panel.limits()$ylim # Debug code print(list(ylim=ylim,xlim=xlim))

I would like to make the print format of the axis value labels appear as ``nn%'' instead of just the numbers. Is there a way to do this? Also, the x axis value labels on my horizontal barplot are rotated 90 degrees (perpendicular to the axis) no matter what I do. I tried las=1 but that didn't work. Is this doable? Thanks. $platform [1] "i686-pc-linux-gnu" $arch [1]

Hi, I'm having a bit of trouble with 'scales="free"' in the segplot() function of latticeExtra. Say we need panels for each year, showing only those counties that are represented in each one: ---<--------------------cut here---------------start------------------->--- library(latticeExtra) data(USCancerRates) uscr.w <- subset(USCancerRates, state ==

Hi, I'm having trouble plotting populations as separate colors and points in the 3d scatterplot package. I have a column with 4 different population names and 3 columns with my data. I want to plot each population with a different color and pch. In addition, I want to use the type="h" in my plotting so that I can see the points clearly in my graph( for publication purposes).

Is there anyway to label axes in 3D plots with mathematical expressions? In the code below, I want to replace "delta_yrsed" with what "\Delta \widehat{yrsed}" represents in TeX, but the [xyz]lab parameters of title3d appear to only accept character strings. require("rgl") fn.delta.yrsed <- function(dist, delta.dist,

I would like to create a 3d scatterplot that is interactive in the sense that I can spin it on its axes to better visualize some PCA results I have. What are the options in R? I've looked at RGL and perhaps it will suffice but it wasn't apparent from the documentation I found. Any demo scripts available for a package that will work? Mark -- Mark W.

In dotplot, what's the best way to suppress the unused levels of 'y' on a per-panel basis? This is useful for the case that 'y' is a factor taking perhaps thousands of levels, but for a given panel, only a handfull of these levels ever present. Thanks, Ben

Hi, I am trying to create a dotplot where each panel shows levels vs. responses; the levels are sorted by responses but levels vary from one panel to another. However, I run into problems with controlling the y-limits and y-labels. In particular, suppose I have a data frame rsp <- c(10,2,4,0,2,3) lvl <-

Hi list, I have a data set - something like this dfr <- data.frame(A=factor(letters[1:25]),B=runif(25), C=sample(LETTERS[1:4],25,replace=TRUE)) and I want to create a dotplot: library(lattice)dotplot(A ~ B | C, data=dfr, scales=list(y=list(relation="free"))) but this puts uneven spaces along the y-axis in each panel. drop.unused.levels=TRUE will drop conditioning

Hello, Is it possible to draw level lines on the surface of a bivariate function? In the following example, to draw surface and levels lines for a multivariate normal law, I use persp, trans3d, contourLines and lines, but if the lines are correctly drawn, some parts of them are, of course, visible even if they are drawn on a non visible "face". Any suggestion to avoid this problem

Hello, I'm using the rgl package and plotting a plot with it. I'd like to have all the axes values auto-hide, but I want to plot a series of characters instead of the values of the measurement for 2 of the axes. So in the end I will have one axis (z actually) behave per normal (auto-hide) and I'd like the other two axes to be custom character vectors that auto-hide. Example: x <-

Hi R-ers, I am struggling with my x-axis in a association plot. What I would like is to place the labels of the x-axis between the tick markers and normally the labels are printed at the place where the tick marker is placed. I don???t want to move the tick marker (it gives the switch between one chromosome and the next) but I just want to put the chromosome number in between the

Have made a stacked area plot, but now want to manipulate the x axis: make in even increments (50) in order to suppress the tick marks (forming solid bar under plot). However, the plot functions do not seem to work, and I cannot find documentation for use of xat in stackpoly. This is a time series of data covering 579 years, and has been successfully converted from zoo to matrix. Data plotting

Dear all, I am fairly new to package Plotrix and I would like to ask you, if any of you could help me with following. a) I don't know how to set up border line width in the Stackpoly function (seems that lwd from par doesn't work, or at least not in the way I have written) b) I don't know, how to rotate the x axis labels (I used srt=45, but same problem as before). c) Could anyone

Hello, I am in need of moderators to help moderate each session. If you are interested, please respond to this mail and indicate which slot you can moderate. Its a long shot as you would miss talks, but if anyone wants a break to do work or check email while also staffing the registration desk, please let me know if you can do it during any of the sessions below.

Hugh, (Note I speak for myself only and not for R-core) Thanks for looking into this. I think it's great to have community members that are interested in contributing to R and helping it continue to get better. And I think, and my local experiments bear out, that using anyNA as a fastpass condition does allow us to get a significant speedup over what's in there now. To do so, though, I
