[R] printing all htest class members

[William Dunlap]

I think you should subclass "htest" and write a print method
for that subclass.  E.g.,

  > print.htest_rb <- function(x, ...) {
  +    NextMethod(x, ...)
  +    cat("all.orders =", x$all.orders, "\n")
  +    invisible(x)
  + }
  > ht2$all.orders <- "THIS IS THE 'all.orders' COMPONENT"
  > class(ht2) <- c("htest_rb", class(ht2))
  > ht2
  
          Test the 'print.htest' method
  
  data:  x 
  Q = 0.0129, df = 2, p-value = 0.9936
  alternative hypothesis: It doesn't print 'all.orders' 
  null values:
    ord df      Q      p
  1   2  2 0.0129 0.9936
  2   3  3 0.0490 0.9972
  3   4  4 0.0684 0.9994
  
  all.orders = THIS IS THE 'all.orders' COMPONENT

If you want the 'all.order' information printed in the
middle of the htest printout then you will have to copy
the code in stats:::print.htest to your print.htest_rb
method and edit it to suit you.
