ExpandData: Expands a CNV input data frame for the maximum likelihood...
In CNVtools: A package to test genetic association with CNV data

Description Usage Arguments Value Author(s) See Also

This function should be invisible to most users. The methods within CNV.fitModel require that the CNV data is expanded N times where N is the number of copies. This allows the use of Generalized Linear Models (GLM) in constraining the Gaussian mixture component locations and spreads to be functions of the copy number.

1	ExpandData(batch, trait, names, signal, ncomp, association.strata = NULL)

`batch`	List of vectors, one vector per batch in the data. Because each element in the list corresponds to a batch, each element should be a vector with a unique values repeated as many times as the number of data point in the batch.
`trait`	List of vectors, one vector per batch in the data. Each element of the list can be either a vector of quantitative traits or a vector of 0 and 1 in a case/control framework
`names`	List of vectors, one vector per batch in the data containing names for each data point, typically individual IDs.
`signal`	List, one vector per batch in the data.
`ncomp`	Integer, number of components one wants to fit to the data
`association.strata`	Optional, a factor vector containing the strata when using a stratified test of association.
