R help - Mar 2006 - {nuSpectral} irreg sampled ts, phase based periodogram

Dear List-mates,

I just read Mathias, et al (2004) about their {nuSpectral} package in R for
a weighted leased squares method for unevenly sampled time-series. 

What kind of experiences have users had with the package?

R-Site Search came up blank. I've never asked about a package that was
downloaded outside of CRAN. Feel free to redirect me as the case may be.

spectral analysis of irregularly sampled time series. Journal of Statistical
Software. 11-2.

Rgds,
