Building an array from matrix blocks
Hello,
I've googled for a while and couldn't find anything on this topic: say
I have a matrix A and want to build matrices B1, B2,... using blocks
from A (or equivalently an array B with B[,,i] being a block from A),
and that I must sum the B[,,i]'s.
I've come up with this rather non-elegant code:
> n = 6
> p = 3
>
> A <- matrix(1:(n^2), n, n, byrow=TRUE)

Defining functions inside loops
Hello,
I was trying to define a set of functions inside a loop, with the loop index
working as a parameter for each function. Below I post a simpler example, as
to illustrate what I was intending:
f<-list()
for (i in 1:10){
f[[i]]<-function(t){
f[[i]]<-t^2+i
}
}
rm(i)
With that, I was expecting that f[[1]] would be a function defined by t^2+1,
f[[2]] by t^2+2 and so on.

rep() fails at times=0.29*100
Dear list,
I have found an unusual behavior and would like to check if it is a
possible bug, and if updating R would fix it. I am not sure if should post
it in this mail list but I don't where is R bug tracker. The only mention I
found that might relate to this is "If times is a computed quantity it is
prudent to add a small fuzz." in rep() help, but not sure if it is related

POSIXct bug for conversion of specific combinations of date and time
Hello everyone,
I'm having a big trouble with which seems to be a bug in as.POSIXct()
date-time conversion. I have massive GPS datasets in which each location
has it's own date and time attribute. As I convert them to POSIXct format,
1300 cases (of about half a million locations) simply return NA values.

Layering multiple persp plots
Hi all,
I've got two persp plots with Identical X and Y's, and I'd like to plot them
on the same graph, so that it is obvious where one plot is above the other.
I can't find any mention of this anywhere. Do I need to use wireframe?
Any help is appreciated.
Thanks,

Greek letters in CairoPDF
Hello there,
Straight to the point: it seems that CairoPDF from package "Cairo"
cannot handle greek letters from expression(). For example,

> f = sin(eta)^2
> pdf(file = "temp_pdf.pdf")
> plot(eta, f, type="l", main=expression(f(eta)==sin(eta)^2), xlab=expression(eta), ylab=expression(f(eta)))

i have a problem using the par function.
in one graphic device i want to have two plots so i tried to use

of course it worked out, but the height now is twice the length of the width
for each single plot.
what i actually wanted is something like par(mfrow=c(2,2)) where only the
