# This is a simple example on how to use the package with the given dataset ZHANG (paired samples):
nameE = "Zhang"
modality1DataColumn = "modality1"
modality2DataColumn = "modality2"
data(zhang)
results = roc.curves.boot(zhang, 10, 0.05, name=nameE,
                          mod1=modality1DataColumn, mod2=modality2DataColumn)
rocboot.summary(results, "modality1", "modality2")
