Performance Plot

Description

Draw for all posible cutoffs, TP, FP, TN, FN, sensitivity, specificity and more.

Usage

performance.plot.ade(pred, event, data=NULL, vnames=NULL, cutoffs=NULL,
                     cutnames=NULL, main=NULL, xlab="cutoff", ylab="%",
                     xlim=NULL, xticks=12,
                     col=NULL, tcol=NULL, bgcol=NULL, lcol=NULL, alpha=NULL,
                     nints=100, lty=NULL, lwd=2, stats=c(1, 2),
                     youden=TRUE, wall=0)

Arguments

pred	a numeric predictor vector a string with the name of the variable in the data.frame a formula yevent~pred
event	a numeric event vector a string with the name of the variable in the data.frame
data	data.frame if used character string for (pred, event)
vnames	a vector of character strings with the labels for performance values in top legend
cutoffs	a vector of optional cutoffs, to draw vertical lines
cutnames	a vector of character strings with the names for optional cutoffs
main	an overall title for the plot
xlab	a title for the x axis
ylab	a title for the y axis
xlim	the x limits (x1, x2) of the plot
xticks	the number of ticks on the x axis or a vector of exact ticks
col	a vector of 4 colors, for the 4 areas in the plot (TP, TN, FP, FN)
tcol	color of the text in whole plot
bgcol	the background color for plot dekoration
lcol	color for the lines in plot, a vector of colors is possible
alpha	a parameter in [0, 1] for semi-transparency of points
nints	number of points for the areas and curves, precision of calculation
lty	a vector of line types
lwd	the line width for all lines, cutoff lines too
stats	a number or vector of numbers from 1 to 4 indicate what statistics are to be drawn 1. Sensitivity 2. Specificity 3. PPV 4. NPV
youden	logical asking whether to plot red line for youden-index maximum
wall	a number between 0 and 6 for selection the dekoration style of the plot.

Examples

performance.plot.ade(rnorm(100), round(runif(100)))
