Using R 2.10 on WinXP
heatmap(mymap, Rowv=NA, Colv=NA)
with mymap values of
0 1 2 3 4
0 NaN 0.000000000 0.00621118 0.0000000 NaN
1 0 0.000000000 0.01041667 0.1250000 NaN
2 0 0.004705882 0.02105263 0.3333333 NaN
3 0 0.004081633 0.02222222 0.5000000 0
4 0 0.000000000 0.01923077 0.1666667 NaN
6 0 0.000000000 0.00000000 0.0000000 NaN
10 0 0.002840909 0.00000000 0.0000000 NaN
20 0 0.002159827 0.00000000 NaN NaN
40 NaN 0.009433962 0.00000000 NaN NaN
(the first row and column are labels, not data)
produces a plot in which all of the row labelled 6 (all 0's and NaN) is
white. This is the same color showing for the NaN values.
In contrast, all other 0 values appear as dark red.
Have I missed some subtlety, or is this a bug?
