Returns a MxN matrix where N is the number of simulations
and M is the number of predicted values. Additionally, a
``labels'' attribute is attached that produces a
human-readable identifier for each column.
Usage
simulation.matrix(obj, which = NULL, ...)
Arguments
obj
an object, typically a ``sim'' or
``pooled.sim'' object.
which
a character-vector specifying the
