apollo_varList

Lists variables names and definitions used in V

Returns a list containing the names and definitions of variables used in V

apollo_varList(
  apollo_probabilities,
  apollo_beta,
  apollo_inputs,
  V,
  cpp = FALSE
)

`apollo_probabilities`	Likelihood function of the whole model.
`apollo_beta`	Named numeric vector of parameters to be estimated.
`apollo_inputs`	List of arguments and settings generated by apollo_validateInputs.
`V`	Named list of functions.
`cpp`	Scalar logical. If TRUE, expressions are modified to match C++ syntax (e.g. x^y -> pow(x,y)). FALSE by default.

It looks for variables in apollo_beta, apollo_randCoeff, draws, and apollo_probabilities. It returns them in a list ordered by origin.

A list containing the following elements (all of type character):

b: Vector with the names of variables contained in apollo_beta.
x: Vector with the names of variables contained in database.
d: Vector with the names of variables contained in draws.
r: Matrix with the names (first column) and definitions (second column) of variables contained in apollo_randCoeff.
p: Matrix with the names (first column) and definitions (second column) of variables contained in apollo_probabilities.
v: Matrix with the names (first column) and definitions (second column) of utilities contained in V.
