#' Shiny bindings for rd3survival
#'
#' Output and render functions for using rd3survival within Shiny
#' applications and interactive Rmd documents.
#'
#' @param outputId output variable to read from
#' @param width,height Must be a valid CSS unit (like \code{'100\%'},
#' \code{'400px'}, \code{'auto'}) or a number, which will be coerced to a
#' string and have \code{'px'} appended.
#' @param expr An expression that generates a rd3survival
#' @param env The environment in which to evaluate \code{expr}.
#' @param quoted Is \code{expr} a quoted expression (with \code{quote()})? This
#' is useful if you want to save an expression in a variable.
