Non-finite values (hence NAs) are no longer allowed
in the parameters.
The rGEV function no longer returns a named
vector.
The probability functions p, d,
q propagate the names of their first argument to the result
and the "gradient" and "hessian" attributes.
This may be useful when working with non-stationary Extreme-Value
models.
The simulation functions rGEV, rGPD2
and rexp1 have an array argument to use the
vectors of parameters in a fashion that is suitable for non-stationary
models, then returning a matrix instead of a vector.
p, d, q
functions did not work with deriv = TRUE when their first
argument contained NAs. This is now possible, the
corresponding rows of the "gradient" attribute and the
corresponding slices of "hessian" attribute contain only
NAs.
