similar to: giving factor names

Tried to post this last night, but it doesn't seem to have appeared. Using R 2.0.1 on Windows XP + SP2. I am traveling, away from my usual references. I'm trying to make a 4-dimensional plot: a levelplot with overlaid contours, with different response variables represented by (1) colors on the levelplot and (2) the contour lines. First try was filled.contour + contour but the key

Hi all, I encountered a difference between versions 1.6.1 and 1.7.0 when using levelplot with an option 'at'. Here are the specs of the two platforms used: > R.version _ platform sparc-sun-solaris2.8 arch sparc os solaris2.8 system sparc, solaris2.8 status major 1 minor 6.1 year 2002 month 11 day 01 language R > R.version _ platform

Hello List! I asked this before (with no solution), but maybe this time... I'm trying to project a surface to the XY under a 3d cloud using lattice. I can project contour lines following the code for fig 13.7 in Deepayan Sarkar's "Lattice, Multivariate Data Visualization with R", but it fails when I try to "color them in" using panel.levelplot. ?utilities.3d says there

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

Here is the answer to an old question of mine, regarding maps in R Hope this help. claudia ---------- Forwarded message ---------- Date: Mon, 25 Jun 2001 13:48:05 -0400 From: Kieran Healy <kjhealy at Princeton.EDU> To: Claudia Tebaldi <tebaldi at ucar.edu> Subject: Re: [R] maps in R Hi Claudia -- you can get the maps() library from here:

I'm fitting data from a mixture experiment, and I'd like to present the results in a ternary graph with contours. I found this code by Walmes Zeviani http://n4.nabble.com/Triangular-filled-contour-plot-td1557386.html which is just what I want--except I would like the axis titles and labels to be proportionately larger than the ternary graph itself, for legibility in publication. When I

Hi, I would like to add contour lines to a (trellis/lattice-) levelplot. Sure, there is the "contour=TRUE" argument, but this uses "cuts=..." (which is usually chosen very high for my plots. I guess cuts=99 is the best you can do (?)) for plotting the contour lines. Furthermore, I do not like the numbering of the contour lines this way. Therefore, I tried to add a

Hello there, I am creating a series of images using levelplot but I also want to overlay a contour for a particular value as reference. Here is the levelplot command for the image: print(levelplot(d~x+y,data=t,cuts=20,scales=list(draw=F),xlab=NULL,ylab= NULL,col.regions=heat.colors(100)[100:1]),split=c(1,1,1,1),more=T) and then to add the contour plot (I only want a contour at level 5):

Dear R-Help community, I am trying to overlay a single contour line over a correlation plot using levelplot in the lattice package. These are the two arrays: 1) a correlation plot over Africa - so each grid square is a different colour dependent on correlation - this is in an array: result_cor with dim[465,465] 2) a single contour line from a ***different data source*** - this is from data

Hello, I want to add a single contour line to a levelplot but can't figure out how to do it 'on-the-fly'. When I include the last line in the code below, I get the following error: Error in NextMethod("[") : Argument "subscripts" is missing, with no default Any tips on how to fix this are greatly appreciated!

Hi. I'm a big user of level plots. Because filled.contour() didn't do exactly what I wanted, I hacked at it a bit to add these options: (*) Even spacing in the key, even if the contours are not evenly spaced. (*) Horizontal key (*) options to not use layout() and to plot only the level plot _or_ only the key. This means you can use layout yourself to (e.g.) have several

Hi everybody, I want to add a single contourline to a levelplot. While everything works fine if the value at which the line should be drawn is positive, there is an error if the value is negative: library(lattice) my.panel <- function(..., at, contour=FALSE, labels=NULL) { panel.levelplot(..., at=at, contour=contour, labels=labels) panel.contourplot(..., contour=TRUE,

Is there an easy way to control smoothness of the contour lines? In the plot I am working on due to the undersampling the contour lines I am getting are jugged, but it is clear "by eye" these should be basically straight lines. In maps package I found smooth.map function, but maybe there is a more generic way of accomplishing the same thing. Ideally there would be an option to control

Dear expeRts, I would like to color a certain region in a levelplot. The region for z <= 0.02 should have a dark gray color. Below is a minimal example. It almost does what I want, but The region between z=0.02 and z=1 is also colored in dark gray (instead of just the region for z <= 0.02). How can I solve this? Cheers, Marius ## z values for given x and y f <- function(x)

With "image" and "contour", one can get both colors and lines to enhance the image of a contour plot. What's the best way to do this with Lattice graphics? The following is one ugly hack, producing the desired result after much trial and error (R 1.9.1 alpha under Windows 2000): # setup DF <- expand.grid(x=1:3, y=1:3) DF$z <- (DF$x+DF$y) # Traditional

Hi, I want to draw a figure similar to http://dsarkar.fhcrc.org/lattice/book/images/Figure_13_07_stdBW.png from http://lmdvr.r-forge.r-project.org/figures/figures.html (figure 13.7) . However instead of using a contour plot as a panel for the wireframe I want to use a levelplot. Can somebody help me with this? Thanks in advance for any help, Kind regards, Anton Bossenbroek

I have two data sets: "new" and "combo". Within both data set, each row pertains to a unique individual. The "combo" data set is a subset of the "new" data set, meaning that all individuals within "combo" are within "new" but not all individuals within "new" are within "combo". Thus, nrow(new) > nrow(combo). Each

I am simulating an ANOVA model and get a strange behavior from the summary function. To be more specific: please run the following code and see for yourself: the summary()[["r.squared"]] values of two identical models are quite different!! ## 3 x 3 ANOVA of two factors x and z on outcome y s.size <- 300 # the sample size p.z <- c(0.25, 0.5, 0.25) # the probabilities of factor z ##

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
