Test for dimorder compatibility

dimorderStandard returns TRUE if the dimorder is standard (ascending), vectorStandard returns TRUE if the dimorder-bydim combination is compatible with a standard elementwise vector interpretation, dimorderCompatible returns TRUE if two dimorders have a compatible elementwise vector interpretation and vectorCompatible returns TRUE if dimorder-bydim combinations have a compatible elementwise vector interpretation.

dimorderStandard(dimorder)
vectorStandard(dimorder, bydim = NULL)
dimorderCompatible(dim, dim2, dimorder, dimorder2)
vectorCompatible(dim, dim2, dimorder=NULL, dimorder2=NULL, bydim = NULL, bydim2 = NULL)

Arguments
