simpleDescriptors: Function "simpleDescriptors"
In peplib: Peptide Library Analysis Methods

Description Usage Arguments Details Value Author(s) See Also Examples

This produces a Descriptors object which is smaller and more simple than those produced by a default call to the normal method for producing descriptors, Descriptors.

1	simpleDescriptors(seqs, response = numeric(0), include.statistics = FALSE)

`seqs`	An `Sequences`
`response`	An optional numeric vector which contains the responses for each sequence in `seqs`.
`include.statistics`	If p-values which estimate the importance of each descriptor are desired, set this to true.

See the descriptors method in Descriptors for details.

A Descriptors is returned. If the statistics were included, the p-values may be accessed in the pvalues slot (value@pvalues).

##Discovering which descriptors are important
