plot.adea {adea}

ADEA plot of standarized virtual input and virtual output

Description

ADEA plot of standarized virtual input and virtual output

Usage

## S3 method for class 'adea'
plot(
  x,
  main = NULL,
  xlab = NULL,
  ylab = NULL,
  labels = NULL,
  labels.pos = 4,
  lcol = "black",
  ...
)

Arguments

x

ADEA object to be plotted

main

if not null then it is used as main in plot. Its default value is the translation of "ADEA efficient frontier". If the adea x has name it is added to the previous value.

xlab

if not null then it is used as xlab in plot. Its default value is the translation of "Virtual input".

ylab

if not null then it is used as ylab in plot. Its default value is the translation of "Virtual output".

labels

if not null then a vector of labels for the DMUs points

labels.pos

position for the labels in the plot. Its default value is 4.

lcol

the color to use to draw the line. Its default value is black.

...

Adittional parameters to plot

Details

This function plots virtual input and virtual outpus in an ADEA model. The virtual input and output vectors are computed as a weighted sum of the inputs and outputs. In addition, it is imposed that the sum of the weights be the unit.

For more information on this calculation process see the references in adea-package.

For the calculations of virtual input and virtual output, the weights generated by ADEA have been used, but they are the same as those that would be obtained using standard DEA.

Value

A list with vinput and voutput values. These values are provided mainly for use with the function identify.
