Description

Creates an image of graduated colors that represent the values of a statistic for each spot on a spotted microarray. By default, the only the 5 shown.

Usage

imgplot(z = coralRG$R[, 1], layout = coralRG$printer, crit1 = 0.05, crit2 = crit1, bar.side = 2, lohi.colors = c("#9E0142", "#D53E4F", "#F46D43", "#FDAE61", "#ABDDA4", "#66C2A5", "#3288BD", "#5E4FA2"), nacolor = "#FFFF00", boxplot.side = 1, split = "quantiles")
