#' Survey of Parents of Children Non-Immunized against Measles  
#'
#' Roberts et al. (1995) report on the results of a survey of parents whose
#' children had not been immunized against measles during a recent campaign
#' to immunize all children in the first five years of secondary school.
#' @name measles
#' @docType data
#' @format Data frame with 11 variables. A parent who refused consent 
#' (variable 4) was asked why, with responses in variables 5-10.
#' A parent could give more than one reason for not having the child
#' immunized. 
#' \describe{
#'   \item{school}{school attended by child}
#'   \item{form}{parent received consent form}
#'   \item{returnf}{parent returned consent form}
#'   \item{consent}{parent gave consent for measles immunization}
#'   \item{hadmeas}{child had already had measles}

#' in the paper.
