setDomain: setDomain
In VBmix: Variational Bayesian Mixture Models

performs linear rescaling of given data.

1	setDomain(dat, span = 10, oldspan = NULL)

`dat`	data to rescale. matrix object, with elements as rows, and variables as columns (i.e. variables are rescaled).
`span`	new domain to which dat is rescaled. If type is numeric and length = 1: [-span, span] is used for all variables. If type is numeric and length = 2: [span[1], span[2]] is used for all variables. If a list object: [span[[1]]_i, span[[2]]_i] is used for each variable i.
`oldspan`	if NULL, old domains are computed from dat inspection. Otherwise, is structured as span and replaces inspected values for rescaling.
