fda 1.2.3

Version 1.2.3 of the fda package has just been released. This version adds to
previous versions a script to create most of the figures of chapter 6 of
"Applied Functional Data Analysis" by Ramsay and Silverman. Other changes
offer simpler calls to time warping / registration and functional principal
component functions.

The fda package supports the books "Functional Data Analysis" and "Applied
Functional Data Analysis" by Bernard Silverman and James Ramsay. Functional
data analysis, which lots of us like to call "FDA", is about the analysis of
information on curves or functions. FDA is a collection statistical techniques
for answering questions like, "What are the main ways in which the curves vary
from one to another?" In fact, most of the questions and problems associated
with multivariate data (PCA, LDA, clustering, ...) have functional
counterparts. More information about FDA can be found at
