when can we expect Prof Tierney's compiled R?
Dear Prof. Tierney, Thank for very much for replying and we all appreciate what you have done for the R community. Currently I have been spoiled by R. I would love to be 100% R. I talked to Andy Liaw yesterday about how to make R faster. Maybe we need to explicitly declare variables in the critical part of R code that intends to be compiled. This is still a much better solution than going to C or Fortran. The new Stata 9 has a matrix language which they claim to be as fast as C. It requires explicit variable declaration. Jason

I hope to be making some substantial progress on this over summer. But I would not hold up any projects in anticipation of major R changes--the current recommended strategy of first writing something that is correct, profiling to find out where a performance problem is if there is one, and then (maybe) optimizing by rewriting R code or coding core bits in C or Fortran is likely to remain the best strategy for a long time to come.

Do you mean the byte code compiler? You can find it at: http://www.stat.uiowa.edu/~luke/R/compiler/ Andy
From: Jason Liao I am excited to learn that Prof. Tierney is bringing to us
compiled R.
I would like to learn when it will be available. This information
will
be useful in scheduling some of my projects. Thanks.
