tabDiv(tab1, tab2)

tabDiv0(tab1, tab2)

tabOp(tab1, tab2, op = "*")

tabEqual(tab1, tab2, eps = 1e-12)

tabExpand(tab, aux, type = 0L)

tabMult(tab1, tab2)

tabSubt(tab1, tab2)

tabListMult(lst)

tabListAdd(lst)

tabPerm(tab, perm)

tabMarg(tab, marg = NULL)

tabSum(tab, ...)

tabProd(tab, ...)

tabNormalize(tab, type = "none")

Arguments

• op: The algebraic operation to be carried out.
• eps: Criterion for checking equality of two arrays.
• tab, tab1, tab2, ...: Arrays with named dimnames (we call them 'named arrays').
• aux: Either a list with names and dimnames or a named array from which such a list can be extracted.
• type: If 0 then entries are duplicated. If 3 then averages are computed. If 2 then 0 slices are inserted.
• lst: List of arrays.
• perm, marg: A vector of indices or dimnames or a right hand sided formula giving the desired permutation/margin.
