I am developing a package for analysis of seismic data that relies on a Fortran library. Package compilation works fine on Ubuntu and Red Hat Enterprise but fails for R 2.15.3 on Mac OSX 10.8.4. I've included the entire dump below but the relevant error message seems to be: ld: warning: ignoring file libmseed/libmseed.a, file was built for...

...''s with my site, will Rails will do the trick? Also, I looked into django, the framework for python. I was sorta intrigued by python because that''s what google uses and I believe yahoo as well. However, there is 0.00% chance of my little ol'' web app ever reaching their seismic proportions, but from what I''ve read django is quite comparable to ruby and quite a bit faster. I guess that''s the only reason why I''m still hesitant about choosing Rails. From what I''ve gathered is that Rails lags in speed and performance. So, why did I choose...

I am using Rwave wavelets and I need better axis notation. Does anyone have code similar to matlab's centfreq or scale2frq functions that turn a scale for a wavelet transform into a good looking scale to plot on my wavelet transfoms? I am using the rwave package to investigate seismic signals from an exploding volcano. Jonathan Lees -- ========================================== Prof. Jonathan M.

...icult to add the NA flag manually. If it's not possible to define the behaviour of the plot(0function, is there another plot I can use, e.g. zoo, that will allow me to not have the lines drawn between the gaps?

...ything which could be relevant but nothing shows at all. I can't think what to do next, has anyone seen this problem before and know a fix? I can provide some more verbose debug output if necessary, I didn't want to output reams of info unless it was absolutely necessary. -- Dougie Dunn Seismic processing systems administrator Fugro-Geoteam Limited

I hope this is merely a FAQ, and not an AFAQ (annoyingly....). I'm a SAS programmer, with several years' experience of the system, evaluating alternatives. See the SAS for Linux website (URL in sig) for more info. I'm exploring R's capabilities and limitations. I'd be very interested in having a deeper understanding of it capacity and performance limitations in dealing with
