graphmod {logilasso} | R Documentation |
Function to plot a graphical model for objects of class
predlogilasso
, cvlogilasso
and levellogilasso
. For
details about graphical models, see reference.
graphmod(obj, grenze = 0, nnames = NULL, ...) ## S3 method for class 'predlogilasso': graphmod(obj, grenze = 0, nnames = NULL,... ) ## S3 method for class 'cvlogilasso': graphmod(obj, grenze=0, nnames = NULL, lambda = NULL, ... ) ## S3 method for class 'levellogilasso': graphmod(obj, grenze=0, nnames = NULL, lambda = NULL, to.which.int = NULL, ... )
obj |
Object of class predlogilasso , cvlogilasso or
levellogilasso . |
grenze |
Components of beta which are smaller than
grenze times the biggest component of beta are truncated to
zero. |
nnames |
Character vector. Names of the nodes in the graphical model. |
lambda |
For object of class cvlogilasso or
levellogilasso : Should not be specified except if the
graphical model for a specific value of lambda should be
drawn. Otherwise this value is assessed by cross-validation. |
to.which.int |
For objects of class levellogilasso : Should
not be specified except if the graphical model for a specific
interaction number is desired. Otherwise assessed by cross-validation. |
... |
Additional arguments to be passed to the plotting function. |
