Defines functions as.regexport.coeftest

Documented in as.regexport.coeftest

#' Coerce coeftest to class regexport
#' 
#' Apply revised standard errors from a coeftest (from package lmtest) to
#' a model and coerce into class regexport.
#' 
#' @param coeftest An object of class coeftest
#' @param model The lm or glm model from which the coeftest was calculated
#' @param sumstats Optional named list of additional summary statistics
#' 
#' @return An object of class regexport
#' 
#' @example 
#' library("lmtest")
#' data("Mandible", package = "lmtest")
#' fm <- lm(length ~ age, data = Mandible, subset=(age <= 28))
#' ct <- coeftest(fm, df = Inf)
#' 
#' as.regexport(ct, fm)
#' 
#' @export
