#' @title Calculate a binomial proportion confidence interval from a sample
#' 
#' @description Uses any of various techniques for calculating a binomial
#'   proportion confidence interval from a sample using the `binom` package
#'
#' @param x Vector of [0, 1] values representing the sample
#' @param method Which method to use to construct the interval. Must be one of
#'   "exact", "ac", "asymptotic", "wilson", "prop.test", "bayes", "logit",
#'   "cloglog", "probit". See `binom` package for details. Default is
#'   "prop.test".
#' @param conf.level The specified confidence level. Defatuls is 0.95.
#' @param na.rm If `TRUE`, NA values will be removed from the sample. If
#'   `FALSE`, NA values will be set to 0. Default is `TRUE`.
