R/data-famuss.R

#' A dataset to examine the relationship between muscle strength and the single nucleotide polymorphism (SNP) actn3.r577x.
#'
#' This dataset is a  subset of the larger data set from the Functional SNPs
#' Associated with Muscle Size and Strength (FAMuSS) by Thompson et.al. It
#' contains demographic, response and coding for the SNP for the study participants.
#' Unlike the data in the previous version of the \code{oibiostat} data package,
#' this dataset retains the missing values. The data are also discussed in the
#' Foulkes text. Strength was measured in both dominant and non-dominant arms
#' before and after resistance training. The particular gene of interest was
#' ACTN3, the "sports gene."
