I can't really tell, because you posted in HTML, but that looks like it was once a perfectly reasonable stem and leaf plot. It's filled with zeros because the R function puts two digits as the stem, and the third digit as the leaves, and for the iris data the third digit is always zero. Compare: data(faithful) stem(faithful$eruptions) Other than that, you'll have to tell us what you think the result should be.
