An object of class ``whatif'', the output of the function
whatif().
type
A character string; the type of plot of the cumulative
frequencies of the distances to be produced, including:
"f" for cumulative frequencies only; "l" for
LOWESS smoothing of cumulative frequencies only; "b" for
both cumulative frequencies and LOWESS smoothing. LOWESS
scatterplot smoothing is plotted in blue and the unsmoothed
frequencies in black. Default is "f".
numcf
A numeric vector; the specific counterfactuals to be
plotted. Each element represents a counterfactual, specifically its
row number from the matrix or data frame of counterfactuals. By default, all
counterfactuals are plotted. Default is NULL.
eps
A Boolean; should an encapsulated postscript file be
generated? Setting the argument equal to TRUE generates an
.eps file, which is saved to your working directory with
file name of form `graph_`type'_`numcf'.eps', where `type'
and `numcf' are the values of the respective arguments. Specifically,
`numcf' takes the value of the first element of the argument numcf
unless all counterfactuals were plotted, in which case all appears in the place of
`numcf'. Default is FALSE, which instead
prints the graph to the screen.
