R packages - Mar 2011 - Package ChemoSpec 1.46 Now Available on CRAN

I'm pleased to announce that the ChemoSpec package is available on  
CRAN for the first time (as version 1.46-4).

ChemoSpec is a collection of functions for plotting spectra (NMR, IR  
etc) and carrying out various forms of top-down exploratory data  
analysis, such as HCA, PCA and model-based clustering. The design  
permits comparison of data from samples which fall into groups such as  
treatment vs. control. Robust methods appropriate for this type of  
high-dimensional data are available. ChemoSpec is designed to be very  
user friendly and suitable for people with limited background in R. A  
vignette illustrating typical operations is available.

Naturally, I'd be glad to hear from users with suggestions and bug  
reports.
