similar to: levelplot border and dendrogram width

I have written a wrapper for heatmap.2 called heatmap.w.row.and.col.clust which auto-generates breaks using breaks<-round((c(seq(from=(-20 * stddev), to=(20 * stddev))))/20, digits = 2) #(stddev in this case = 2.5) This has always worked well in the past but now I am getting an error that non-finite breaks are being generated. Drilling down, it seems that my wrapper is generating finite

I'm using this code to create a heatmap of expression data and indicate a specific column of data, post clustering: #Generate heatmap: heatmapChipDx <- heatmap.2(L3data_med2, dendrogram="column",trace="none", col=redgreen(64), colsep=seps, sepcolor="yellow", sepwidth = 0.1, margin=c(5,5), scale="row", key=FALSE) I have two problems that I'm

I am using attributes colsep and sepwidth from heatmap.2 function, however when using larger values for sepwidth the following columns are not moved to the right but the seperator is covering the column(s) with a white bar and the column labels and ColSideColors remain at their positions, is this intended? I expected the following columns to be shifted to the right by sepwidth. Is there a way

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

Hi, I'm using the latticeExtra package's dendrogramGrob function to create a grob with both a dendrogram and a covariate bar (via the 'add' parameter). When the dendrogram has very short branches at its leaves, it appears as a line and becomes impossible to see when placed next to the covariate bar. For example: > x <- outer(-5:5, -5:5, "*") + matrix(nrow = 11,

I'm suppressing the labeling of my rows and columns in heatmap.2 using the commands: labRow = " ", labCol = " " But I'd like to annotate them again using the axis command: axis(1, at=seq(500, 1000, 500)) mtext("Group 1", "Group 2") For some reason however it appears that the axis command is having no effect. My complete

heatmap.2 defaults to dist for calculating the distance matrix and hclust for clustering. Does anyone now how I can set dist to use the euclidean method and hclust to use the centroid method? I provided a compilable sample code bellow. I tried: distfun = dist(method = "euclidean"), but that doesn't work. Any ideas? library("gplots") library("RColorBrewer") test

Dear all, I am using the heatmap representations of latticeExtra package and I would be interested to draw color side bars representing the groups of a factor of interest. From my understanding of : > help(dendrogramGrob) ... The 'add' argument can be used for additional annotation at the base of the dendrogram. It should be a list with one component for each row,

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).

Hi, I would like to report a problem with the levelplot borders in lattice. Description: The borders in levelplots appear when running in a Windows setting, however running the identical command in Linux does not generate the plot with the borders. The commands used were: library(lattice) levelplot(volcano, border = 'black', shrink = c(0.7, 0.7)); The same version of R (2.13.0) and

I would like to use gridBase to place four separate heatmaps (actually, a stripped-down heatmap.2 from ght gregmisc package that contains only the "image" part) into four different viewports. I can get the placement correct, but I keep 'losing' the previous plot. Any suggestions? Here is some quick example code trying to put a heatmap into the left viewport and then

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

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
