#' Load simulated genotypes in the FBM format.
#'
#' The function loads the matrix of simulated genotypes
#' with 1,500 samples (rows) and 200 genetic variants (columns).
#' Genotypes are coded as 0, 1 and 2 (the number of alternative alleles).
#' All variants have the minor allele frequency fixed to 0.5.
#'
#' @return An object of class FBM. 
#' @examples
#' G <- attach_example200()
#' G
#' G[1:5, 1:10]
#'
#' @export
attach_example200 <- function()
