[Rd] Need to tell R CMD check that a function qr.R is not a method

[Henrik Bengtsson]

Would a workaround (for pleasing R CMD check) be to do:

qr.R <- function(...) UseMethod("qr.R", ...)

qr.R.qr <- function(qr, complete, pivot) {
  # No need to assert the class of 'qr' here.
  ...
}

Haven't tried it.  Method dispatching may also add unnecessary
overhead if called lots of times.
