Description

Funtions to access data from the benchmark dataset registry entries

Usage

S4 (GEDdata_entry)
`exprs`(object)

S4 (GEDdata_entry)
`dims`(object)

S4 (GEDdata_entry)
`basis`(object)

S4 (GEDdata_entry)
`coef`(object)

S4 (GEDdata_entry)
`nbasis`(x)

Arguments

object
an object of class GEDdata_entry as returned by GEDdata_registry$get_entry.
x
an object of class "factanal" or "princomp" or the loadings component of such an object.

Value

a numeric matrix

a matrix

an integer

Methods

  1. basissignature(object = "GEDdata_entry"): basis access/compute the signatures and mixture Proportions.

  2. coefsignature(object = "GEDdata_entry"): coef returns the mixture coefficient matrix (i.e. the proportions) available for the data.

  3. dimssignature(object = "GEDdata_entry"): dims gets the dimensions of an ExpressionMix object. It returns a 3-length integer vector, containing the number of features, samples and components respectively.

  4. exprssignature(object = "GEDdata_entry"): exprs loads and extracts the expression matrix from a registry data entry.

  5. nbasissignature(x = "GEDdata_entry"): nbasis returns the number of constituents signatures available in the data.
