tfplot.rootsEstEval: Specific tfplot methods for rootsEstEval (EstEval) objects

Description

See the generic function description.

Usage

## S3 method for class 'rootsEstEval':
tfplot(x, ...)
    ## S3 method for class 'rootsEstEval':
plot(x, complex.plane=TRUE, cumulate=TRUE, norm=FALSE,
       bounds=TRUE, transform=NULL, invert=FALSE, Sort=TRUE, ...)

Arguments

x

an object for which a tfplot is to be produced.

complex.plane

logical indicating if the plot should be on the complex plane.

cumulate

logical indicating if the cumulative average of roots should be plotted

invert

logical indicating if the inverse of roots should be plotted

Sort

logical indicating if the roots should be sorted.

...

arguments passed to other methods.

norm

logical indicating if the euclidean norm of roots should be plotted (square root of the sum of squared roots).

bounds

logical indicating if estimated one standard error bounds should be plotted around the lines for the true roots.

transform

an optional string indicating the name of a function which should be applied to the roots before plotting.

Details

If complex.plane is TRUE then all results are plotted on a complex plane and the arguements cumulate and Sort do not apply. If complex.plane is FALSE then a sequential plot of the real and imaginary parts is produced. If cumulate is true the cumulative average is plotted. If mod is true the modulus is used, otherwise real and imaginary are separated. if invert is true the reciprical is used (before cumulating). if Sort is true then sort is applied (before cumulate but after mod) by the Re part of the root. Some grouping is usually necessary since roots are not in an obvious order but sorting by the real part of the roots could be improved upon.
