[R] color question

[Aimin Yan]

I have a question about assigning color based on the value of a matrix

The following is my matrix.

d
             lateRT      earlyRT         NAD       ciLAD
lateRT  1.000000000 0.0000000000 0.006224017 0.001260241
earlyRT 0.000000000 1.0000000000 0.001425649 0.007418436
NAD     0.006224017 0.0014256488 1.000000000 0.064653780
ciLAD   0.001260241 0.0074184361 0.064653780 1.000000000
LAD     0.006969928 0.0007096344 0.393556636 0.002483941
                 LAD
lateRT  0.0069699285
earlyRT 0.0007096344
NAD     0.3935566356
ciLAD   0.0024839407
LAD     1.0000000000

I want to use the following function to get heatmap and dendrogram

> heatmap.2(d,trace="none",margin=c(8, 10))

but it is hard to use color to make  0.001260241 and 0.0074184361 to be
visualized differently.

Does anyone know how to adjust color based on these values in this matrix?

Thank you,

Aimin
