formulaUnimva {mvabund} | R Documentation |
Create a list of m univariate formulas given a formula with multivariate response of dimension m.
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.
