How to create a heatmap in R- one row at a time?

Question

I'm new to R and am trying to generate a heatmap as part of a pipeline that will later on associate the heatmap with metabolic pathways. I have data in an excel file in the following form:

         tissue1   tissue2  tissue3  ...  
gene1          5         3        1  
gene2        120       400       70  
gene3          0         3        0  
...

My goal is to have some kind of a function or method I can call and it will only generate a heat map for the appropriate row, something like heatmap(gene2). I have roughly 800 rows. I want each heatmap to have an independent scale (indep on the other rows) Is it possible?

Thanks! :)

Answer 1

with artificial data, if this is what you want.

x=matrix(abs(rnorm(100))*100,10,10,)
image(as.matrix(x[1,]))
