mefaCheck {mefa} | R Documentation |
The functions evaluates the internal structute of a 'mefa' object.
mefaCheck(x) mefaCompare(x1, x2, strict = FALSE)
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. |
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.
