Wait a minute. Over Christmas holiday, people had something better to do?

Gotta say, the {ellmer} package is robust and pretty darn easy to use. Nicely done, Dr. Wickham!

@matloff.bsky.social @datavisfriendly.bsky.social I have a "small-ish n" problem, the covariance of short-ish time series. The EWMA cov estimate worked pretty well, but the matrix was not invertible ("uncooperative"). The cov.shrink function gave an invertible matrix; and the shrinkage was a bonus.

OMG. @eddelbuettel.com points out that the correct spelling of the function is `cov.shrink`. Thank you, Dirk! #mybad

You are in very good company, my friend. You are not alone. Be brave. #zzzzz

Thank you! Your comments and code example are very useful. This whole S7 thing is looking quite good. Time to get my hands dirty.

Thank you. That is quite helpful, actually. Seeing someone work thru their use-case is great.
