dimorderCompatible

Test for dimorder compatibility

Description

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.

Usage

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

Arguments

`dim`	a `dim`
`dim2`	a dim
`dimorder`	a `dimorder`
`dimorder2`	a dimorder
`bydim`	a bydim order, see `[.ff`
`bydim2`	a bydim order, see argument `fromdim` in `update.ff`

Value

TRUE if compatibility has been detected, FALSE otherwise

Note

does not yet gurantee to detect all compatible configurations, but the most important ones
