[R] registration density profiles : FDA

[Bellanger Lise]

Hello,


       I would like to use  fda library to compare sampled curves that 
are density profiles. But I encounter some problems to register my data :
I know that I must use a registration function to align functions in 
order to have important features found in each curve occur at roughly 
the same argument value, prior to do subsequent analysis ( PCA and 
cluster analysis).   But I do not know which function (if there exists 
one) allows me  to synchronize density profiles : could help me please ?

   Thank you by advance

   Best regards

         Lise Bellanger
