Hi all, i am using heatmap.2 function for coloring my heatmap. Every time the color scheme that i am using results in either greenish or reddish heatmap. I want to anchor the black color to the "0" value and the color gradient follows uptill the maximium value in the heatmap. For anchoring black color to the "0" value i have tried the heatmapCol function from library(MKmisc) but there is no color change after the minimum value of the dataset. Please give me suggestions that i should follow. Any relevant reply will be appreciated -- Ankhee Dutta project trainee, JNU,New Delhi-67 [[alternative HTML version deleted]]
