#' easily write a csv file compatible with nonmem
#' @details 
#' nonmem uses '.' for NA values, does not like quotes in column names
#' and does not handle row names, so these are all presets
#' @param x dataframe to be written to csv
#' @param file character string naming a file or connection open for writing.
#' @param sep field string separator, defaults to comma (",")
#' @param row.names logical value whether to include row names
#' @param na value for NA
#' @param quote whether character or factor columns should be surrounded by double quotes
#' @param ... remaining arguments passed to data.table::fwrite
#' @examples \dontrun{
#' write_nonmem(nonmemdat, 'folder/nonmemdat.csv')
#' }
#' @export
