deaR (version 1.2.1)

plot.dea: Plot for DEA models.

Description

Plot some attribute of a DEA model (conventional, fuzzy or Malmquist).

Usage

# S3 method for dea
plot(x, showPlots = TRUE, ...)

Arguments

x

An object of class "dea" obtained by a dea model function.

showPlots

Logical. When TRUE (default) the plots are shown one by one. When it is FALSE the plots are not shown and are returned by the function (invisiblily) as a list.

...

Ignored, for compatibility issues.

Value

Depending on the model it returns a single data.frame containing: efficiencies, slacks, lambdas, targets, references or a list of data.frames with the cross-efficiencies computed with different methods (Arbitrary, Method II or Method III (see CITA)) or, in case the model is a malmquist index, a single data.frame with the coefficients for the different periods.
