%description
Algorithms for accelerating the convergence of slow, monotone sequences
from smooth, contraction mapping such as the EM and MM algorithms. It can
be used to accelerate any smooth, linearly convergent acceleration scheme.
A tutorial style introduction to this package is available in a vignette
on the CRAN download page or, when the package is loaded in an R session,
with vignette("turboEM").
