DET 3.0.3

• Added and updated maintenance files:
  • show.R: corrected display behaviour for DET objects.
  • measures.R: added objects to the output of minDcf().
  • plot.R: corrected DET and ROC curve plots with confidence intervals, axis labels, and zoom options.
  • detc.R: corrected the names of the positive and negative labels.
• Small code modernisation and polish.

DET 3.0.2

• Minor changes to restore DET to CRAN.

DET 3.0.0

• Added class objects to model DET curves.

• Overrode the standard plot() function when called with a DET or DETs object.

• Renamed printDET() to show().

• Added new functions to compute performance measures: EER() and minDcf().

• Added new functions to plot the corresponding ROC curve from a DET curve: plotROC() and plotROCs().

DET 2.0.1

• printDET() shows the names of the classifiers used to access the DET object.

• detc() and detc.CI() do not plot the EER. The examples describe how to do this.

• Added the speaker and ovarianCancer data sets to provide real examples of DET curves.

DET 2.0.0

• Added printDET() for describing the DET returned parameters.

• Renamed det() and det.CI() as detc() and detc.CI() to avoid overriding existing functions.

• New detc() and detc.CI() functions now provide an estimate of the Equal Error Rate in the returned data frame.

DET 1.0.1

• Updated the appearance of ROC curve plots.

• det() and det.CI() now include xlim and ylim arguments to select the axis limits of the plot.
