If you just want a coloured representation of your distance matrix, use image()
If you want to cluster your original data and show the original data (not the distances) as a heatmap then use heatmap(), but you should use something like hclust() to cluster the data first.

Subject: [R] heatmap
I am having troubles with heatmap(). I have a matrix containing pairwise
distance values and I want to plot this matrix with heatmap. I wonder
now what distfun is for. Is a distance matrix computed from my initial
matrix again and then plotted?
