Optimized Rendering of Fold Changes and Confidence Values

Shows color patches for encoding fold changes (e.g. log ratios) together with confidence values within a single diagram. This is especially useful for rendering gene expression data as well as other types of differential experiments. In addition to different rendering methods (ggplot extensions) functionality for perceptually optimizing color palettes are provided. Furthermore the package provides extension methods of the colorspace color-class in order to simplify the work with palettes (a.o. length, as.list, and append are supported).

This package allows to show fold changes together with confidence values within a single diagram using the patch grid method. Furthermore psychophysical optimization of color scales are supported.

For more details have a look into the vignette of this package.
