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.
