\title{All Components of a (Inner or Outer) Nested Archimedean Copula}
\description{
  Given the nested Archimedean copula \code{x}, return an integer vector of the \emph{indices} of all components of the corresponding \code{\linkS4class{outer_nacopula}} which are components of \code{x} (either direct components or components of possible child copulas). This is typically only used by programmers investigating the exact nesting structure.

  For an \code{\linkS4class{outer_nacopula}} object
  \code{x}, \code{allComp(x)} must be the same as
  \code{1:\link{dim}(x)}, whereas its \dQuote{inner} component copulas
  will each contain a \emph{subset} of those indices only.
}
\usage{
allComp(x)
}
\arguments{
  \item{x}{an \R object inheriting from class \code{\linkS4class{nacopula}}.}
}
\value{
  An \code{\link{integer}} vector of indices \eqn{j} of all components \eqn{u_j} as described in the description above.
