Hi any one help me to draw heat map, i am having the three samples microbial diversity data, i wish to draw heat map in R statistics anyone replay how to upload data into R and draw heat map

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:
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?
HI! I appreciate that this has been a long time since your question, but you or anyone else reading this may be interested in this. I just developed a Julia-based GUI tool to plot heatmaps based on Python's Seaborn package, just for the reason you wanted. Though it doesn't make use of R. Just 10-15 min to get it running. Very minimal/no coding is required for this. Just need to click to input .xlsx/.csv/.txt files and a heatmap would be produced. At the minute, only heatmaps are supported. In the near future, additional plotting types and functionalities will be supported. This is the link with the full information and instruction:

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
This question has been asked before on biostars: How to draw a Heat map for gene expression data?
+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
