In enrichvs: Enrichment assessment of virtual screening approaches

Description

Function to plot a enrichment curve with a logarithmic scale on the x axis

Usage

	plot_enrichment_curve_xlog(x, y, decreasing=TRUE, npoint=100, 
		colbarwidth=1, colorize=FALSE, add=FALSE, col="black", lwd=2)

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
npoint	the number of points to plot the curve
colbarwidth	the width of color bar (only if colorize==TRUE)
colorize	TRUE if the plot line is colorerd by the corresponding scores
add	TRUE if the plot is add to the previous plot
col	color of the plot
lwd	line width of the plot

Value

call a plot

Examples

data(dud_egfr)
x <- rnorm( 88888 )                        # virtual scores for 1000 compounds
y <- c(rep(1,88), rep(0,88800))            # activity labels for "x"
plot_enrichment_curve_xlog(x, y, col="blue")

plot_enrichment_curve_xlog(dud_egfr$energy, dud_egfr$label, 
	add=TRUE, decreasing=FALSE, col="red") # Add a plot
legend("topleft", legend = c("ideal", "random", "score1", "score2"),
	lty=c(2,3,1,1), col=c("black", "grey", "blue", "red"), bty="n")
