This seems like a basic R usage question rather than a specific bioinformatics problem, so the answer would be "you need to learn how to use R."

try to add actual data and desired output in your questions to make it answerable for us.

I put some code here before A: Superimpose 2 heatmaps

Heatmap using R, with special conditions !!! might be quite close

+1 on Neilfws's response. There are MANY tutorials on how to draw a heatmap in R, just use google, they are out there. This is not a strictly bioinformatics question, rather a question about a common way to communicate data.

You didn't give us much information on what you are doing? You mention "three samples microbial diversity data" and I'm wondering if you mean to draw a correlation map (such as Pearson's, Spearman's etc. etc.) as they are a type of heat map and not a heat map of transcript data?

Hello,

For R clustering there is an easy way in Galaxy. Go to the toolshed https://toolshed.g2.bx.psu.edu/ and look for tool named heat_map_creation. It is explained how to run on YouTube It allows one to enter a input matrix and uses R clustering techniques (you select from menu) and creates a heatmap to visualize in Galaxy as well.

Another way is via a self-contained Docker container Sincerely, Dr. Bob

Nice tutorial. But it does not handle multiple side color bars. The last plot in the tutorial is heatmap.2. This function is improved by heatmap.3 How Do I Draw A Heatmap In R With Both A Color Key And Multiple Color Side Bars?

ggplot2 and heatmap plus are two easy to handle R packages! Check them out:

Most likely you want to make a heatmap with the following options:

  • Plot a dendrogram of clustering on both colums and rows of the heatmap
  • Plot multiple sample information colors on rows or columns
  • A legend that tells you how the intensity of the colors corresponds with the values that went into the heatmap

If you want all three of them, then you can either use ggplot2 but you will have difficulties with aligning the dendrogram plots with the heatmap. You will have to do something nasty like playing the viewport settings. Or you can go with the How Do I Draw A Heatmap In R With Both A Color Key And Multiple Color Side Bars?
