pdf device: rasterize portions of the plot to reduce file size
Dear list, My favorite output format is usually pdf. I can include the graphics in pdflatex documents and benefit from the scalable nature of vector graphic formats. However, I recently had to generate high-res 2D levelplot graphics as in the example below, N <- 100 # N <- 1000 # slow to diplay xy <- expand.grid(x=seq(0, 10, length=N), y=seq(0, 10, length=N)) xy <- within(xy,

Problem with levelplot() in a loop
Dear R users, I am trying to print heatmaps in a loop (with a pause). Idea is to visualize changing correlations over time and for testing I wrote this simple (reproducible) code below. My problem is that levelplot() does not produce any output when I run the code (though heatmap does). Ideally I would like to use levelplot() as it produces a neat index on the side indicating the color and the

centering axis labels in lattice
Hello, I'm attempting to alter the location of text in my axis labels in lattice plots and have been unsuccessful so far. For example, the y-axis labels are always right-justified, but I would like them to be horizontally centered. Here's an example: library(lattice); # create fake dataset to plot to.plot <- data.frame( x = 1:5, y = c("1\nAAA", "2\nBBB",

Heatmap without levelplot
Hi there, as I'm not sure to understand the coloring levelplot uses, I'm looking for another easy way to create a heatmap like this: library(lattice) mat <- matrix(seq(1,5, length.out = 12), nrow = 3) mat[1,2] <- 3.5 my.at <- seq(0.5,5.5, length.out = 6) my.col.regions <- rainbow(5) graph <- levelplot(t(mat[nrow(mat):1, ] ), at = my.at, col.regions = my.col.regions)

adjusting levelplot color scale to data
Hi guys, I have a matrix with values varying from approximately -0.7 to 0.33 that I want to create a heatmap/levelplot with. When I execute the levelplot function for my matrix, I end up getting colors that are adjusted to the max and min rather than around 0. In other words, ideally I would like to have a color ramp that goes from red (negative number), to white (0), to blue (positive);

heatmap with levelplot?
Hi, How do I anchor z=0 to the white color in a levelplot so that the color changes from cyan to magenta precisely as z changes from negative to positive? Also is it easy to change color scheme, say to blue/red as it's more dramatic? Is there a better function for showing heatmap with a color bar? Thanks in advance for any help, I've played with image, heatmap and levelplot a little and

heatmap with levelplot
Hi there, I'd like to create a heatmap from my matrix with a) a defined color range (lets say from yellow to red) b) using striking colors above and below a certain threshold (above = "green", below = "blue") Example matrix (there should be a few outliers generated...) + simple levelplot without outliers marked: library(lattice) my.mat <- matrix(rnorm(800), nrow =

levelplot/heatmap question
Hello! I have data containing a large number of probabilities (about 60) of nonzero coefficients to predict 10 different independent variables (in 10 different BMA models). i've arranged these probabilities in a matrix like so: (IV1) (IV2) (IV3) ... p(b0) p(b0) p(b0) p(b1) p(b1) p(b1) p(b2) p(b2) p(b2) ... where p(b1) for independent variable 1 is p(b1 !=

Lattice 3d coordinate transformation
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

Levelplot without margins

levelplot in lattice
Hi, I'm new to lattice. So please kindly be patient with me. I'm trying to arrange groups of levelplots into 3 rows as follows: Row1: Probabilities as functions of x and y, and conditioned on an event factor vector factor("a","b","c") Row2: Number of days as functions of x and y, and conditioned on, again the same event

How can I make a lattice::levelplot block size uniform
Dear lattice::levelplot users, I would like to use levelplot to plot uniformly sized blocks. Here is an example: require (lattice) u = runif(10) * 10 v = runif(10) * 10 z = runif(10) levelplot ( z ~ u + v, aspect="iso" ) The resultant figures have points (blocks) that are of variable size that attempt to fill in the space along each u, v dimension. Is it possible to force each point

xyplot/levelplot: thickness of tickmarks
Hi, if I use the xyplot (or levelplot) function (lattice library) with the option axs="i", I have the problem that the tickmarks lie a bit outside the "plot-box". Consider for example: library(lattice) x<-seq(0,1,by=0.01) y<-seq(0,1,by=0.01) xyplot(y~x,type="l",xlim=c(0,1),ylim=c(0,1),scales=list

Lattice levelplot- remove unused levels per panel
Hi, I am using levelplot, and would like remove from each panel (condition) its unused x levels. e.g. Remove from panel vs=1 the cyl level=8. data(mtcars) levelplot(mpg~factor(cyl)*factor(gear)|factor(vs)) Thanks for your help, Ronny -- View this message in context: http://r.789695.n4.nabble.com/Lattice-levelplot-remove-unused-levels-per-panel-tp4656087.html Sent from the R help mailing

Layout within levelplot from the lattice package
Hi, I'm a novice with levelplot and need some assistance! Basically, I want a window which contains 6 levelplots of equal size presented in 3 columns and 2 rows. I've tried to approach it two ways. The first way leads to this question: Is there any way to concatenate levelplots from a factor vertically as opposed to horizontally? I'd like to pair the levelplots by factor.2 on

lattice: how to add points to the plot generated by levelplot()?
I am using levelplot() function from pkg:lattice and I want to add some points to the plot generated by levelplot() similarly as in basic R graphic sequence: plot(...); points(...), but it does not work. I was reading documentation for lattice, but so far without much success. I would very much appreciate some tips. Best regards, Ryszard

decrease amount of ticks on y axis in lattice levelplot
Hi all, How can I decrease the number of ticks on the y-axis in a lattice levelplot()? I have as many ticks displayed on the y-axis as I have columns of data (1000 columns), how can I decrease this amount of ticks, while still properly displaying all the data? Note that I get my data from a matrix object, in which the z-values of the levelplot are the actual values in the matrix, whereas the

lattice levelplot axis + custom annotations
How would I set the "scales" property of a lattice levelplot, so that I can add specific annotations at specific positions? For example, I have a 200 x 1000 element levelplot. Along the y-axis (along the 1000-element axis) I would like to add annotations on the left side of the levelplot at elements 120, 300, 500, and 805, which represent clusters of interest. Currently I have

multiple lattice, xyplot & levelplot on same page
Dear R-users, I'd like to place an xyplot() at the top of a page and a levelplot() at the bottom of the same page, and have the x-axes be the same. I've come close to finding a solution through Rarchive, and can produce an upside-down version of what I'd like (levelplot() on the top - see code below). However, the following error occurs when I try and plot the xyplot() at the top:

[R] proposal: lattice/levelplot: panel.catlevelplot
I suggest to add a panel function to levelplot (or perhaps to an other 3d lattice function) which is able to translate the z values into the size of the rectangles. It could be used to display categorical data. I append the proposed code and two examples: - panel.catlevelplot() - example1.catlevelplot.esoph() - example2.catlevelplot.esoph() Wolfram Fischer #------ CODE
