Hello, All:

          fda_2.2.8 (functional data analysis) is now available on CRAN. This revision includes the following improvements:

  1. A bug in pca.fd has been fixed.
  2. Many functions have a new argument "returnMatrix", which if TRUE allows the function to use the sparse matrix representations in library(Matrix). This should allow users to solve some larger problems and provides a speed advantage in a few cases.
  3. A few other minor bugs have been fixed including problems with some of the script files in system.files('scripts', package='fda').

          A package using the returnMatrix argument will also need Matrix in the dependencies in DESCRIPTION and something like import(Matrix) in NAMESPACE. Each use will require adding returnMatrix = TRUE to an appropriate fda function call.

       Best Wishes,
Jim Ramsay, Giles Hooker, Spencer Graves
