[R] beginner's problem in displaying large data

[Spencer Graves]

	  Are you sure you are only getting the last 5 columns, rows 1723:2200? 
  There isn't a scroll bar some place?

	  What do you get from the following?

      (tst <- data.frame(array(rnorm(500), dim=c(500, 6))))

	  This should come in 2 sets of 500 rows, the first with 5 columns, the 
second with only 1.  If what you said earlier is accurate, I would guess 
that when this is done, the screen would display rows 23:500 of column 
6.  Is this what you get?

	  If you still have troubles, check "?sink", pipe the output to a text 
file file, and look at the file with some other application, e.g.:

	  sink("huh.txt")
	  (tst <- data.frame(array(rnorm(500), dim=c(500, 6))))
	  sink()

	  hope this helps.
