plot method for ROC curves
plot method for ROC curves
plots an ROC curve object, with additional parameters available:
should marker threshold values be plotted?
should plotted points be jittered?
increment to current plot?
plot points or lines?
if showing threshold values, set
character expansion in text call to this value
if showing threshold values, add this quantity to y coordinate of curve to plot the threshold value (should be negative for printing below point)
if showing threshold values, use
this as the digits parameter to round to display the
threshold
extra parameters passed to base
plot, lines or points as needed
set.seed(123) R1 <- rocdemo.sca( rbinom(40,1,.3), rnorm(40), dxrule.sca, caseLabel="new case", markerLabel="demo Marker" ) plot(R1, line=TRUE, show.thresh=TRUE, lwd=2, threshDig=2) R2 <- rocdemo.sca( rbinom(40,1,.3), rnorm(40), dxrule.sca, caseLabel="new case", markerLabel="demo Marker" ) plot(R2, line=TRUE, add=TRUE, col="green", lwd=2 ) R3 <- rocdemo.sca( rbinom(40,1,.4), rnorm(40), dxrule.sca, caseLabel="new case", markerLabel="demo Marker" ) points(R3, col="red", pch=19)
