similar to: Fwd: [R-sig-hpc] Holtman's levelplot ?

Looking for a recommended package that handles prime number computations. Tried the following unsuccessfully: primeFactors() in the R.basic package failed to install. primes() and primlist are broken in Schoolmath pkg on CRAN. My analysis can be found here http://j.mp/9BNI9q Not sure what the procedure is for getting things fixed, so I've cross-posted to r-dev as well. --njg

Hi - I have a levelplot with positive and negative z-values. I'd like to scale the levelplot rectangles proportional to the *absolute* z-values to highlight the z-value extremes (while retaining the color difference to track the positive/negative attribute). I've likely missed something in the documentation, but have been at it a couple days without finding a solution (other than

Dear all; I have a data set with 3 groups and 2 response variables, say z1 and z2, and I would like to create a single plot (using the levelplot function) showing on the first row the leveplots for z1 for each group and on the second row levelplots for z2 for the same groups. I tried plot.trellis using the split option and it's OK but what I would like to achieve is something similar to what

I just tried rendering a plot of 166 data point (time series) on my PPC mac, and compared it with the same data rendered by Mathematica. The R plotting is very slow to paint and repaint, compared to Mathematica. This also makes it extremely awkward to use in other documentation such as pdfLatex. On closer inspection, it looks like the Mathematica plot is just a polyline, while in R it is a

I am trying to display data ion top of colored rectangle on the same levelplot. While using superpose the shape and symbol for levelplot changes to small circle. I am unable to figure what exactly I am doing wrong... It may be straightforward solution... .I will appreciate help to fix this issue.

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):

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!

Dear R communities May I seek your advices on how to change color the default in levelplot(), e.g. from the default of pink and light blue, to e.g. red and green ? The levelplot function has 1 of the arguments being panel (which is actually panel.levelplot), but I am not sure where the commands to alter the color. For example, I type: p1<-levelplot(my.mat,colorkey=FALSE), how could I

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 guRus, I'm having trouble producing a levelplot with relative cuts for each panel (my data has large differences in scales, so I want to use quantiles for each panel). My attempts to change the 'at' argument in panel.levelplot function have not met with success. Below is a toy example. xy <- expand.grid(x = 1:3, y = 1:3) aaa <- rbind(cbind(xy, z = 1:9, site =

Hi, I like to produce a series of levelplot graphs in postscript file, so I put the trunk of codes including postscript() and levelplot() in a for loop. The codes work fine outside the loop, but only produce empty .ps file when being put within the loop. Is it a problem associated with postscript() or levelplot()? How to get around the problem? Many thanks! Yan [[alternative HTML

Hello, I have encountered some unexpected behaviour with levelplot that may simply be a misunderstanding on my part. If I create a levelplot from a matrix with named columns, some "padding" space appears at the top and bottom of the heatmap. Here is an example, and I've used panel.fill to make the space I'm speaking of evident (in green).

Dear mailing list, I am trying to find out, how do a levelplot without labels on the x- and y-axis. The labels=FALSE does not work...can anyone help me? m <- matrix(1:25, ncol=5) levelplot(m, labels=F) Regards, Benedikt

I'm a new user of levelplot, and are not familiar with the terminology very well. Is the bar alongside the levelplot indicating color or shade call "colorkey"? I have to adjust the size of its label, but couldn't make it so far. This is how I did: levelplot(z~x*y, grid, at=seq(0,1,by=0.1), colorkey=list(labels=list(cex=2))) But I got error message "Error in

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

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

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

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

Dear R users, I have changed my R version to the new 1.8.1 and some problems appears when using the previous levelplot code. This is a simple example: a <-1:10 b <-11:20 j <- rnorm(100) grid<-expand.grid(a = a, b = b) levelplot(j~a*b, grid) Normaly in my previous vs this was suffice to produce the levelplot. Now, an empty R graphics device appears with the following error
