plot.confint {chandwich}  R Documentation 
plot
method for class "confint".
Plots the (profile) loglikelihood for a parameter using the values
calculated by conf_intervals
.
Up to 4 different types of loglikelihood (see the argument type
to the function returned by adjust_loglik
)
may be superimposed on the same plot.
By default (add_lines = TRUE
) the confidence limits calculated
in conf_intervals
are indicated on the plot .

x, y, y2, y3 
objects of class "confint", results of calls to

which_par 
A scalar specifying the parameter for which the plot
is produced. Can be either a numeric vector, specifying index of the
component of the full parameter vector, or a character scalar
parameter name. The former must be in 
conf 
A numeric vector of values in (0, 100). If

add_lines 
A logical scalar. Whether or not to add horizontal lines to the plot to identify the confidence limits. 
legend 
A logical scalar or a character vector. If this is
supplied then a legend is added to the plot. If 
legend_pos 
The position of the legend (if required) specified using
the argument 
... 
Additional arguments passed to 
Nothing is returned.
See the examples in conf_intervals
.
adjust_loglik
to adjust a usersupplied
loglikelihood function.
conf_intervals
for confidence intervals for
individual parameters.
conf_region
and plot.confreg
to
plot a confidence region for a pair of parameters.
