I have a file of the following form
-11 -10 -9 -8
-10 -9 -8 NA
-9 -7 NA NA
-8 NA NA NA
So basically a NxN matrix of log scores. I want to get a heatmap of these
log scores but I'm having a problem.
I'm using the following code
library(gplots)
data=read.table("filein.txt",header=FALSE)
mat=as.matrix(data)
heatmap.2(mat,dendrogram=c("none"))
But on the picture, it rearranges all my row,columns. I want it the y axis
to be labeled from [10,-10] and the x axis to be the same [-10,10] so that
the bottom left cell is -10,-10 and the top right cell is 10,10 -- which is
the way the matrix is laid out. Why is it rearranging my cells?
