You're right about the code preceding .C. I stripped down the .C and
.Call codes to be as similar as possible, and the timings were much
closer.
R code:
Call_matrix_multiply = function(A,B){
C <- matrix(0,nrow(A),ncol(B))
.Call("R_CALL_matrix_multiply", A, B, C)
return(C)

I recently found a solution to the RMySQL compiling problem.
You however there is one additional requirement at present (with the MySQL
server version 5.5 & R2.12.1) follow the
http://biostat.mc.vanderbilt.edu/wiki/Main/RMySQL instructions at present as
the locations of the libmySQL.dll differs

How should we translate something like the following?
Tcl> bind Frame {%W config -bg red}
such that the widget id (and other % substitutions) can be accessed
in R callback?
one <- tkframe(width=30, height=30)
tkbind("Frame",

I just tried that myself and the .Call version is substantially
faster. It seems like there is a lot more going on in the .Call C
code than the .C. Why is .Call faster? Does it have to do with the

and NAOK=TRUE, but .Call was
So it seems that there is something wrong with the liblzma library

since a few days, my package hyperSpec does not build on r-forge. I have no idea
whether this is due to my code or whether something is wrong with r-forge.
