Could anyone tell me how to plot a hierarchical clusterin g in a black-white color?
Try using the argument col=gray(seq(0, 1, length=64)), or something like that. Andy
From: Frank Duan Dear R people, I am trying to do a hierarchical clustering to a matrix using heatmap() function. But I like to have the plot to display in a black-white manner? Could anyone tell me how to do that? Thank you. Frank
