Dear sirs, My name is Marcelo Grimaldi and i work for General Electric in the Six Sigma Program. Recently I became very interested in spectral analysis, because I think it can be applied to my job. I use Minitab 12 and i have heard that writing macros for spectral analysis in this software is very difficult. Could I perform this analysis in a easier way throught "R" ? Have you ever heard about anybody that perform it using "R"? I would apreciatte very much if I could get in touch with these specialists.

Yes, through some built-in code and through an additional package. I don't know about "getting in touch with the specialists", though -- your best bet is to start with a good general-purpose time series analysis book, which will have something about spectral analysis and will lead you to more specialized references. Or start from whatever references suggested spectral analysis to you in the first place. Or follow interesting references in the documentation of the R functions. If you have a working knowledge of R (from reading documentation and the various public domain guides accessible through CRAN, or the books listed at CRAN) and a reasonable knowledge of spectral analysis it should be quite straightforward to use the SA tools in R. It's best to save R-help for specific problems with R, although the occasional interesting statistical problem will probably get responses ... [If I were a better Perl programmer I would write a script that would try to answer "Can R ... ?" questions automatically by (1) searching the help pages on CRAN, (2) searching the package sources, (3) searching the mail archives ...] On Mon, 15 Jan 2001, Castro, Marcelo T G (GEL, MSX) wrote:> > Dear sirs, > > My name is Marcelo Grimaldi and i work for General Electric in the Six Sigma > Program.
