RKeOps does not support direct encoding of argument in the formula without an alias in the argument list. This function check if any argument are directly encoded in the formula without an alias.

text string, an operator formula (see Details).
Ghislain Durif
Parse the formula for string such as
"YY(<pos>,<dim>)" where YY can be a formula input argument type
(Vi, Vj or Pm), <pos> is the position of the corresponding input
argument, and <dim> its inner dimension.
"Var(<pos>,<dim>,<type>)" where <pos> and <dim> are the position and
inner dimension (c.f. previous point) and <type> is an integer encoding
the formula input argument type with the following relation:
|---------|-------------------------|-----------|
| keyword | meaning | type |
Vi | variable indexed by i | 0 |
Vj | variable indexed by j | 1 |
Pm | parameter | 2 |
| --------- | ------------------------- | ----------- |
