R heatmap with different color scales for different rows

I am wondering what would be an easy solution to produce heatmaps() with of composed data that require different scaling for different rows.

So in my case the columns represent different events of the same type, and the rows are different observations of these events that can be binary开发者_JAVA技巧 or diff. continuous data.

F.ex:

Event: ev1 | ev2 | ev3 | ev4 | ev5 | ev6
Obs1:   1  |  0  |  1  |  1  |  0  |  0
Obs2:  5.6 | 0.2 | 4.8 | 7.1 | 0.1 | 0.8

Thanks in advance for hints and help

To have a single heatmap where different rows have been scaled differently would be rather confusing, since you would need a legend for each shading. This would quickly clutter up the plot.

If you suggest that you don't need a legend, then simply scale your values to range between zero/one and you should get would you are after. So for Obs2 you would have something like:

scaled_obs2 = (Obs2 - min(Obs2))/(Obs - min(Obs2))
