Hello Hans,
I put an example for heatmap.2 with colored dendrograms and additional
text under

Hello Hans,
Do you need *both* a categorical *and* a continuous variable, or just a
continuous variable?

Hello Greg,
I want to visualize survival data above the columns. So my continuous
variable is follow up time and my categorical variable indicates the
event. As the event has only two states (death or alive), one probably
can omit an extra side bar for this variable and represent it by
different colors within the plot for the follow up time. If it is
easier to place two annotations above the heat map, that would be
fine, too.
Probably the simplest solution is: Just plot numbers (follow up times)
in red (death) or blue(alive) above the columns. (Analogous to the
sample names under the columns.) I do not know how to do this.
Regards,
Hans-Ulrich

Dear All,
I want to plot a heat map with annotated columns. Both functions
heatmap
(stats) and heatmap.2 (gplots) can plot a horizontal side bar that can
be used to visualize a categorical variable. In addition to a
categorical variable, I would like to visualize a continuous variable.
This could be done by small bars, a curve or simply numbers above the
columns. (The Sample names are already located at the bottom.)
Does someone have example code for this or a similar problem? Is
this so
special that I have to get down to the lattice package?
Thank you,
Hans-Ulrich
