These functions implement a classifier to classify three classes of pathway membership of the RasMAPK and JNK pathway. For each sample and each channel a sparse linear discriminat classifier is trained. The posterior probabilities are averaged over all single classifiers. The classification posterior probabilities of three classes are plotted as a ternary plot (ternary plot adapted from CRAN package vcd).
Genetic interaction surfaces are estimated from a dilution experiment. Cells are treated with two RNAi's. The concentration of the RNAi reagent is changed in 8 steps. All 8 x 8 combinations of concentrations are tested for 6 x 6 gene pairs.
This functions provides a grid plot that displays the raster image of a heatmap without any axis or label. This function is adapted from the function grid.sgiHeatmap from the package RNAinteract-package. It is highly recommended to use the original function grid.sgiHeatmap.
This function is a reimplementation of smoothScatter. For nicer graphics output the background image is written by grid.raster. It is recommended to use the smoothScatter function from the graphics package.
