Re: [R] Asymmetric colors for heatmap

Sorry, my mistake, I did not realize that image() has breaks and that heatmap() inherits from image(). However, I have the following problem, maybe I am doing something wrong. I have defined: mycol <- c("blue1","blue2","blue3","blue4","black","yellow4","yellow3","yellow2","yel low1") breaks<

Maybe, it is not possible to normalize correlation coefficients? Would a barplot comparing the correlation coefficients between two genes for different tissues be meaningful? (Alternatively, I have tried to use (1-pval) to calculate the gray-level of the bars.) Any further suggestions would b

Dear all Just for fun, I have just downloaded the paper mentioned below and checked it with R-1.6.1. Everything is ok with exception of Table 2b, where I get always 1 instead of 0.5: > pbinom(1e15,2e15,0.5) [1] 1 Which value should be correct? Best regards Christian Strat
