Description

FIXME

Usage

parse_extra_args(formula, args)

Value

a list with different information about formula input arguments: a list with different information about formula input arguments:

var_type

vector of text string, corresponding type of formula arguments (among Vi, Vj, Pm).

var_pos

vector of integer, corresponding arguments positions.

var_dim

vector of integer, corresponding arguments dimensions.

Arguments

Details

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 | |---------|-------------------------|-----------|
