[R] [R-pkgs] Introducing the makeit package

, it can provide the same functionality as GNU Make but with fewer software requirements in terms of software installed and system path. The make calls() can be grouped together in a dedicated script, called something like _make.R, or conveniently called from within scripts to decide whether

Re: [R] an alternative to R for nonlinear stat models

As far as I can tell, Gove et al. (2002) might be a good example for benchmarking the optimization performance of R vs. ADMB. It would be great if expert R users/developers could tweak Beni's model so that the performance comparison is valid. The main purpose is not to see which is faster or m

Re: [R] an alternative to R for nonlinear stat models

It has been brought to my attention that the 1997 benchmark was updated in 2006, using R instead of S-Plus. and a newer computer, obviously. The result was that ADMB converged more than 1000 times faster than R. The model is an ecological population model, not unlike Gove et al. (2002). Anyone

[R] Autocorrelation in linear models

I have been reading about autocorrelation in linear models over the last couple of days, and I have to say the more I read, the more confused I get. Beyond confusion lies enlightenment, so I'm tempted to ask R-Help for guidance. Most authors are mainly worried about autocorrelation in the resi
