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, ...)

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.

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.
