Hi List, sorry if this is a FAQ : I could not make my way to it :-( Once upon a time it happened to be a package named "rpm" for "Robust Point Matching". I can find a few traces of it in the CRAN archives : works by Saussen and al. (Aligning spectra with R), but can't find the package anymore. No trace at all in the "Old" or "Orphaned" lists.... Does one UseR know about it, or even use it ? Thanks in advance, and regards to all.
