R packages - May 2012 - new version of fda fixes bug in pca.fd and supports library(Matrix)

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
