Log Message:
(graphics/R-effects) Updated 4.1.1 to 4.2.1

Version 4.2-1

 o Allow the vcov. argument in the call to one of the effect methods
 to be a matrix or a function.  Previously only a function was
 permitted.

 o Fixed bug in plot.eff() for multiline plots in which the x.var
 argument is set explicitly (reported by Gerrit Eichner).

 o Small improvements to docs.

Version 4.2-0

 o Adding the use of the insight package to get formulas.

 o Added Effect.glmmPQL() for fitting generalized linear mixed models
 using the glmmPQL() function in the MASS package for penalized
 quasi-likelihood estimation.

 o Don't ignore lines lty sub-argument to plot.effpoly() (fixing a bug
 reported by Laura Adamovicz).

 o One-column matrix predictors trigger a warning and correction
 (following problem reported by Carla Hendricks).

 o Added regression tests for classes of model objects
 supported. Tests must be enabled in the effects sources at
 tests/regression-tests.R.

 o Rewrite of defining effect method vignette.

 o Minor changes to predictor effects gallery vignette.

Version 4.1-4

 o Change class(x) == "y" to inherits(x, "y") in code.

Version 4.1-3

 o Handle xlevels=n argument correctly in Effect() (fixing bug
 reported by Gerrit Eichner).

 o Add col argument to effectsTheme(), mostly to accommodate
 colorblind-friendly palette (suggestion of Sercan Kahveci).

Version 4.1-2

 o Effect methods for clm, clm2, and clmm models were not correctly
 passing the estimated theshholds to polr for computing effects (error
 reported by Stefan Th. Gries).

 o Updated "Defining Effects Methods ..." vignette to reflect
 revisions to Effect.clm, Effect.clm2 and Effect.clmm.

 o Make sure that Effect() and plot() methods work correctly with
 character and logical predictors (following bug report by Julian
 Gaviria Lopez).
