require(foreign) require(MASS) require(bootES) library(ggplot2) library(plyr)# might be not needed here anyway it is a must-have package I think in R library(reshape2)# to "melt" your dataset library (scales)# it has a "rescale" function which is needed in heatmaps library(RColorBrewer)# for convenience of heatmap colors, it reflects your mood sometimes require(beanplot) library(plyr)# For the desc() function library(ggplot2) library(crop) library(directlabels) library(scales) library(grid) library(moments)
