I am sorry that I mostly did not respond to your stemplot efforts. I was having trouble with my email client and am now using gmail.
I didn't specify that gaps in the stems should be filled in with empty "stems" in the stemplot, as shown below. Would you be willing to revise your solutions? I should be able to respond now. The request is for a stemplot verb. data =: 17 133 151 47 12 19 52 80 32 87 24 14 20 90 9 47 72 7 36 64 stemplot data 0|7 9 1|2 4 7 9 2|0 4 3|2 6 4|7 7 5|2 6|4 7|2 8|0 7 9|0 10| 11| 12| 13|3 14| 15|1 Here is the original (incomplete) specification. >From Moore and McCabe, Introduction to the Practice of Statistics, Fourth Edition, page 20 -- To make a "stemplot": 1. Separate each observation into a "stem" consisting of all but the final (rightmost) digit and a "leaf", the final digit. Stems may have as many digits as needed, but each leaf contains only a single digit. 2. Write the stems in a vertical column with the smallest at the top, and draw a vertical line at the right of this column. 3. Write each leaf in the row to the right of its stem, in increasing order out from the stem. -- Sent from Gmail Mobile ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
