Blomberg et al.'s Correlation Structure

The ``ACDC'' (accelerated/decelerated) model assumes that continuous traits evolve under a Brownian motion model which rates accelerates (if $g$ < 1) or decelerates (if $g$ > 1) through time. If $g$ = 1, then the model reduces to a Brownian motion model.

Usage
corBlomberg(value, phy, form = ~1, fixed = FALSE)
## S3 method for class 'corBlomberg':
corMatrix(object, covariate = getCovariate(object),
                   corr = TRUE, ...)
## S3 method for class 'corBlomberg':
coef(object, unconstrained = TRUE, \dots)
Value

an object of class "corBlomberg", the coefficients from an object of this class, or the correlation matrix of an initialized object of this class. In most situations, only corBlomberg will be called by the user.
