#' Get descriptives relatives to Island
#'
#' Get counts, proportions and plots for relative position to Island CpGs attending to any criteria as Bonferroni, FDR
#'
#' @param position string. CpG relative position to Island (Island, N_Shelf, N_Shore, OpenSea, S_Shelf, S_Shore )
#' @param criteria boolean. Boolean with criteria like Bonferroni, FDR,...
#' @param namecriteria string, criteria name for plot and to add to descriptives
#' @param outputdir string. Output path to store file with results, by default results are written in current dir
#' @param outputfile string. File name to store results if no name is provided results are not written.The suffix "_DescIslands.txt" and "_PlotIslands.pdf" are added respectively for descriptive file and plots.
