mefaCheck: Check and Compare Object(s) of Class 'mefa'

In mefa: Multivariate Data Handling in Ecology and Biogeography

Check and Compare Object(s) of Class 'mefa'

Description

The functions evaluates the internal structute of a 'mefa' object.

Usage

mefaCheck(x)
mefaCompare(x1, x2, strict = FALSE)

Arguments

x, x1, x2	an object of class 'mefa'.
strict	logical, if TRUE the function checks if ordering of dimnames are the same, otherwise it compares only matching.

Value

mefaCheck returns a list, first element is logical with TRUE indicating that all requirements are met. If this is FALSE, following elements of the list describe the encountered problems as characters. mefaCheck is called by the is.mefa function.

mefaCompare compares two mefa objects. If all dimnames, and the corresponding values in the xtab and segm parts are identical, the result is TRUE, and otherwise FALSE. Different ordering of dimnames allowed, the comparison is based on the numeric values determined by dimnames.
