Re: [R] Sending lists from R to C using .C

Hi Chris, I personally found the documentation rather...indigestible. At least 3 years ago when I developed my R package. It seems they have nicely improved this part of the documentation though. I'm not an expert at all, but at least you will have the point of view of a beginner. First, i

Here is a simple example: > mylist <- replicate(4, matrix(rnorm(12), ncol=3), simplify=FALSE) > A <- Reduce( `+`, mylist ) > B <- mylist[[1]] + mylist[[2]] + mylist[[3]] + mylist[[4]] > all.equal(A,B) [1] TRUE Basically what Reduce does is it first applies the function (`+` in this case) to the 1

Re: [R] How to adjust the distance between legend and the plot (xyplot)

Hi, Peter, Thanks. This is exactly what I am looking for! Just a little concern. Since there are so many parameters in the trellis.par, how do we even know there is one that can do what we want? The documentation does not really have that much details. Jun On Mon, Apr 16, 2012 at 4:29 PM, Peter

Re: [R] Effeciently sum 3d table

That _is_ interesting. Reduce() calls the sum function at the interpreted level, so I would not expect this. Can you check whether most of the time for my "vectorized" version is spent on the do.call(cbind ...) part, which is what I would guess. Otherwise, this sounds strange, since .rowSums is spe
