  The decimal point is at the |

  6 | 9

  8 | 00003

> y <- c(x, 8)
> stem(y)

  The decimal point is 1 digit(s) to the left of the |

  68 | 0
  70 | 00
  72 | 000000
  74 | 00000
  76 | 00
  78 | 0000
  80 | 00000
  82 | 0
The first stem is as I want it to be and expect it to be. When I add one more observation R seems to add an extra decimal zero to my observations and all leaves are now zero. Why does this happen?
