NeatMap: Non-clustered heatmap alternatives  original paper BMCBI 11 45

http://cran.r-project.org/web/packages/NeatMap/index.html

NeatMap is a package to create heatmap like plots in 2 and 3 dimensions, without the need for cluster analysis. Like the heatmap, the plots created by NeatMap display both a dimensionally reduced representation of the data as well as the data itself. They are intended to be used in conjunction with dimensional reduction techniques such as PCA.
