Time for action – the spine plot for the shift and operator data

Spine plots are drawn using the spineplot function.

  1. Explore the default examples for the spine plot with example(spineplot).
  2. Enter the data for the shift and operator example with:
    ShiftOperator <- matrix(c(40, 35, 28, 26, 40, 22, 52, 46, 49),nrow=3,dimnames=list(c("Shift 1", "Shift 2", "Shift 3"), c("Operator 1", "Opereator 2", "Operator 3")),byrow=TRUE)
  3. Find the number of non-conforming parts of the operators with the colSums function:
    > colSums(ShiftOperator)
     Operator 1 Opereator2  Operator 3 
            118         121          99

    The non-conforming parts for operators 1 and 2 are close enough, and it is lesser by about 20 percent for the third operator.

  4. Find the number of non-conforming parts according to the shifts ...
