#' Applies the \code{\link{netfacs}} function across multiple levels of the
#' condition and puts them in a list
#'
#' Take dataset and report observed and expected likelihood that elements and
#' combinations of elements occur in this dataset, and whether this differs from
#' a null condition. Expected values are based on bootstraps of null
#' distribution, so the values represent distribution of element co-occurrence
#' under null condition. The resulting object is the basis for most other
#' functions in this package.
#'
#' @inheritParams netfacs
#' @param condition character vector of same length as 'data' that contains
#' information on the condition each event belongs to, so probabilities can be
#' compared across conditions
#'
#' @return An object of class \code{netfacs_multiple}, which contains the
#' probabilities of observing element combinations in one condition vs. all
#' other conditions, along with other useful information. The resulting object
#' is the basis for most other functions in this package.
