Hi I am having some problems getting my heatmap to be the right size! Let me explain. I am experienced at getting an hclust or a dendrogram object to be the right size.
For example, I have a dataset which has 4000 rows, which I clustered using hclust and I wanted to plot it as a horizontal dendrogram. So I used jpeg(), set the image height to be 4000 and plotted the dendrogram and got the result I expected - ie the dendrogram filled up the whole image and I had roughly one pixel per row of data. However, if I run heatmap() instead of hclust(), the resulting image DOES NOT fill up the whole jpeg() - instead, it sits right in the middle of it, the same size as it would be if I had ran heatmap() normally into an x11() window. I've figured out how to use the margins= argument of heatmap() to set the margins, but how do I make my heatmap fill up all of the available space in a jpeg()?
