similar to: heatmap-changing column or row names

The function heatmap() allows to specify row/column labels via the options labRow/labCol. From the code of heatmap(), I understand that when no labels are specified, the row/column labels (or indices) of the input matrix are taken as labels and re-ordered together with the rows and columns of the matrix before plotting, whereas labels supplied via labRow/labCol are plotted in the original order.

Dear All, There might be a bug in heatmap(): x <- matrix(rnorm(10*5), 10, 5) heatmap(x, labCol=1:5) Error in axis(1, 1L:nc, labels = labCol, las = 2, line = -0.5, tick = 0, : 'at' and 'labels' lengths differ, 5 != 10 Works fine under 4.0.1. Looking at the code from 4.0.1 vs. Rdevel, esp. this part sticks out: labRow <- labRow[rowInd] %||% rownames(x) %||%

Hi, I wanted to make more than one side color bar. For example, I can make one side color bar (col1) with the following code: ----------------------------------- library(gplots) mat <- matrix(sample(1:100,40),nrow=5) class1 <- c(rep(0,4),rep(1,4)) col1 <- ifelse(class1 == 0,"blue","red") class2 <- c(rep(1,3),rep(2,5)) col2 <- ifelse(class2 ==

I'm trying to display the probability space of a function and wanted to see specifically where the maximum posterior probability is. data=read.table("PosteriorData",header=F) mat=as.matrix(data) heatmap.2(mat/max(mat,na.rm=T),dendrogram=c("none"),trace=c("none"), Rowv=F,Colv=F,labRow=3*c(10:-10),labCol=3*c(-10:10),symm=T,col=rainbow(100)) As the

Hi, Is there a way I can draw an abline on a heatmap? I try the abline function, but don't get the line. My sample code is: mat <- matrix(sample(1:100,40),nrow=5) heatmap(mat,col=greenred(75),trace="none", dendrogram = "column",labCol = NULL) abline(h=5,v=4) thanks! [[alternative HTML version deleted]]

I am using heatmap with the arguments below. The title size stays the same no matter what I set cex.main to. Is this expected? Can I adjust the title size in heatmap? Also, the position of the main title is at the very upper edge of the output and if I use a "\n" to stack the title the upper line is out of bounds and doesn't show up. I am outputting to pdf. Any help? Thanks,

Hello All, I have a simple question based on how things are labeled on my heat map; particularly, there is this annoying "X" that appears before the numeric value of all the labels of my columns. Let's say I have the following silly data, stored in "temp.txt" 1905 1910 1950 1992 2011 2020 Gnat 0.08 0.29 0.29 0.37 0.39 0.43 Snake

Hi, I am using heatmap.2 of gplots to make heatmaps of my the attached file. I am giving my code for the same .. library(gplots) x=read.table("1.txt", header=TRUE) mat=data.matrix(x) heatmap.2(mat, col=greenred(75), Rowv=TRUE, Colv=TRUE, distfun = dist, hclustfun = hclust, dendrogram = c("both"), scale = c("row"), na.rm=TRUE, trace="none",

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 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

Hello R Gurus, I have a matrix for which I am doing a heatmap using heatmap.2. I want to put the rownames on the lefthand side instead of the right side of the heatmap. how can i put the rownames on left hand side: I have already tried axis but could not make it work ccc<-structure(c(1, 0.283300333755851, 0.237863231117007, 0.0148696794159253, -0.0780756406815149, -0.106161465097659,

Dear R users, I'm trying to create images of 2 symmetrical matrices using heatmap.2 of the 'gplots' library. Both matrices have the same row and column names For the first matrix I'm using the default clustering and column denrogram options: heatmap.2(Matrix1, symm=T, breaks=20, col=rich.colors(19), main="matrix1", density.info="histogram",

Hi, i created a graph with heatmap(sma) function: heatmap(dataHeat(x)) and I wish to change the gradation of colors from blue to red, how could i do? Using "heatmap(dataHeat(x), col=c(2,4))" i will use only 2 colors without gradation. Ty so much Andrea

I would like to organize my data as follows: I have a table that contains various data, and the numbers represent a level of similarity between these data, eg RF00013 has 100% similarity with the data RF00014. I would leave my table as a heatmap where darker colors represent higher similarity, and the lighter colors represent less level of similarity. I'm using version 2.11 of R. these

Hi, I am drawing a heat map using gplots of R package. The file (new4) is having values 0 and 1 only. library(gplots) library(marray) x=read.table("new4", header=TRUE) mat=data.matrix(x) heatmap.2(mat, col=colorRampPalette(c("black","red"))(256), #col=greenred(75), Rowv=TRUE, Colv=TRUE, distfun = dist, hclustfun = hclust, dendrogram = c("row"), scale =

I have a huge dataset(15k X 18) and tried to use the heatmap in R to examine the patterns. However, I found that heatmap and heatmap.2 gave me completely different outputs. Here are the codes: ------------ > dim(as.matrix(data.dcpm)) [1] 15462??? 18 > > heatmap(as.matrix(data.dcpm), col=topo.colors(100)) > heatmap.2(as.matrix(data.dcpm), col=topo.colors(100), key=TRUE,

I am having trouble displaying a dendrogram of evolutionary relationships (a phylogram imported from the ape package) as the vertical component of a heatmap, but keeping the hierarchical clustering of the horizontal component. The relationships of the vertical component in the generated heatmap are not that of the dendrogram, although the ordering is. In more detail, I am attempting to generate

Hi, I'm kinda new of the R world. I need to use the heatmap or heatmap.2 function to plot correlation values. 2 questions: - how can I specify a color palette? (would like to have a transition from blue(-1) to white(0) to red(1)) - how can I use heatmap.2 imposing a specific order (like hclust.order)? I mean, I don't want heatmap.2 to re-cluster/re-order my data but just to plot them

Hi, I have a question about the heatmap dendrogram in R. I loaded my data matrix in command heatmap(), and it gave me a heatmap accordingly, and the rows (genes) also were clustered accordingly. But now I don't want the genes clustered in that way, I have a new order of these genes, and want the rows of the heatmap are drawed as the order I give. Could anybody help me on that? Thank you!
