Not according to the documentation...
sort(x, partial = NULL, na.last = NA, decreasing = FALSE,
method = c("shell", "quick"), index.return = FALSE)
na.last: for controlling the treatment of `NA's. If `TRUE', missing
values in the data are put last; if `FALSE', they are put
first; if `NA', they are removed.
