Dear r-users,
 
I would like to construct tem and leaf plot using iris data.  It should be easy, but I don't understand why the plot is not right.
 
Thank you so much for your help.
 
dat <- iris[,1] > stem(dat)  The decimal point is 1 digit(s) to the left of the | 42 | 0 44 | 0000 46 | 000000 48 | 00000000000 50 | 0000000000000000000 52 | 00000 54 | 0000000000000 56 | 00000000000000 58 | 0000000000 60 | 000000000000 62 | 0000000000000 64 | 000000000000 66 | 0000000000 68 | 0000000 70 | 00 72 | 0000 74 | 0 76 | 00000 78 | 0
