Examples

##Finding correlation with a response
data(AMPSequences)
data(AMPSequences.response)

AMP.desc <- simpleDescriptors(AMPSequences, response=AMPSequences.response[,1])

print(cor(AMP.desc))

##Discovering which descriptors are important

data(TULASequences)

TULA.desc <- simpleDescriptors(TULASequences, include.statistics=TRUE)
print(TULA.desc@pvalues)
