#' Creates a remote directory with the specified group ownership and permissions.
#'
#' If the directory already exists, attempts to set the group ownership to the
#' \code{user.group}. The allowed group permissions are one of
#' \code{c("g+rwx", "g+rx", "go-w", "go-rwx")}, or \code{"-"}. The value
#' \code{"-"} means "don't change permissions".
#' @param path Directory path. If using \code{remote}, this should be a full path or
#' a path relative to the user's home directory.
#' @param user.group The user group. If NULL, the default group is used.
#' @param remote Remote machine specification for ssh, in format such as \code{user@@server} that does not
#' require interactive password entry. For local execution, pass an empty string "" (default).
#' @param permissions The group permissions on the directory. Default is 'rwx'.
#' @rdname mkdir.remote
#' @note This may not work on Windows.
# COMPATIBILITY WARNING: WINDOWS
