title: R heatmap.2 skip column or row labels
body: <p>I am trying to plot a matrix of values over a range using heatmap.2. The columns are the range (for example, 0 to 100). There are too many column labels to display clearly. Is there a way to display every Nth one (0, 10, 20, etc)? I want all the values to be displayed, but I just don't want them all to be labeled.</p>
