os.plot {optiscale}

Graph of optimal scaling transformation

Description

Line and point plot showing optimally-scaled values on the vertical axis, original data values (assumed to be qualitative) on the horizontal axis.

Usage

   os.plot(x.qual, os.data, 
      main.title = "Plot of optimal transformation")

Arguments

x.qual

Vector of data values, assumed to be qualitative.

os.data

Vector of optimally-scaled data values.

main.title

Main title for plot.

Value

Object of class trellis.

Examples

  ###   x1 is vector of qualitative data
  ###   x2 is vector of quantitative values
            x1 <- c(1,1,1,1,2,2,2,3,3,3,3,3,3)     
            x2 <- c(3,2,2,2,1,2,3,4,5,2,6,6,4)     
  ###   Optimal scaling, specifying that x1
  ###   is ordinal-discrete
     op.scaled <- opscale(x.qual=x1, x.quant=x2,   
                  level=2, process=1)              
  ###   Plot of optimal scaling transformation
     os.plot(op.scaled$qual, op.scaled$os)
