Plot the gain curve of a sort-order with costs.

Plot the gain curve of a sort-order with costs.

GainCurvePlotC(frame, xvar, costVar, truthVar, title, ...)

Arguments

frame	data frame to get values from
xvar	name of the independent (input or model) column in frame
costVar	cost of each item (drives x-axis sum)
truthVar	name of the dependent (output or result to be modeled) column in frame
title	title to place on plot
...	no unnamed argument, added to force named binding of later arguments.

Examples

set.seed(34903490)
y = abs(rnorm(20)) + 0.1
x = abs(y + 0.5*rnorm(20))
frm = data.frame(model=x, value=y)
frm$costs=1
frm$costs[1]=5
frm$rate = with(frm, value/costs)
frm$isValuable = (frm$value >= as.numeric(quantile(frm$value, probs=0.8)))
