Thanks a lot..! What exactly the sweep function is doing? Also, is there a possibility instead of using the mean of the whole row to get only the mean of a group of the row values? So the values in the matrix (heat map) used in the comparison are z-scores and not the intensities of the gene express

[R] heatmap.2: question regarding the "raw z-score"

Hi, I am analysing gene expression data using the heatmap.2 function in R and I was wondering what is the formula of the "raw z-score" bar which shows the colors for each pixel. According to that post: https://mailman.stat.ethz.ch/pipermail/r-help/2006-September/113598.html, it is the (actual val

[R] heatmap.2 question

Hi, there, I am planning to use heatmap.2 function to draw some heatmaps. However, I don't want to use default set manhattan distance and complete linkage in heatmap.2. How should I change parameters distfun and hclustfun? Thank you. ys [[alternative HTML version deleted]] _
