ratdat: Portal Project Teaching Database

#' Complete survey data from 1977 to 1989.
#'
#' Data on individual rodents captured at the Portal Project and the plots they were captured in. This data.frame is the same as `complete`, but only containing data from 1977 to 1989. This is so that instructors can have learners begin working with a clean, older dataset, and later introduce a messy version of the newer years of data, in whatever format fits their needs.
