Create a List of Univariate Formulas

Create a list of m univariate formulas given a formula with multivariate response of dimension m.

Usage

formulaUnimva(formula, var.subset, split.x=FALSE, intercept=0,
  allow.noresp=FALSE)

formula: a formula or a mvformula, the elements are not allowed to be data.frames.
var.subset: optional vector of the variable numbers to use.
split.x: logical, whether explanatory terms that are matrices should be split and each added as a single term. this is useful for plotting formulas.
intercept: numeric, either 1 if an Intercept should be included in the formula or 0 if there shouldn't be an Intercept in the formula.
allow.noresp: logical, whether an empty response is allowed (a list with one element would be returned) or not (would result in an error.)

A list containing m formulas with the univariate responses chosen by var.subset.
