Arguments

x

a vector for scores

y

a vector for labels (0:inactive, 1:active)

decreasing

TRUE if the compounds are ranked by decreasing score

nplot

the number of plots

colbarwidth

the width of color bar (only if colorize==TRUE)

• call a plot

Examples

x <- rnorm(1000)    # random scores for 1000 compounds
y <- c(rep(1,50), rep(0,950))     # activity labels for "x"
plot_enrichment_curve(x, y)

data(dud_egfr)
plot_enrichment_curve(dud_egfr[,1], dud_egfr[,2], add=TRUE, decreasing=FALSE, col="red")
