Hi r users,
I am trying to compute the "moving variance" of a large matrix. I now use a
loop but I am looking for a faster solution. Here is a sample of the code.

Dear Deepayan,
Thank you for pointing out those functions. They will be helpful to me. If
you don't mind, I may get back to you on that topic if I cannot find a way
to apply them to my actual problem (the example I gave was just for
illustration). This problem is more complex and involves multiple
Thanks David. Is there a way of explicitly passing the rowname since I
need it in the function.

Make two assumptions:
(1) The initial state probability distribution (``ispd'') is *NOT* a
function of the
transition probability matrix (``tpm'').
(2) The boxes are stochastically independent of each other.
Both of these assumptions may be dubious. The second assumption is
the crucial one
Dear Allan,
thank you very much for your answer.
If I got it right your idea is
a: create first all the i,j combinations and then
b. use mclapply (parallel version of lapply).
so I wrote some draft and run three experiments:
# code
require('multicore')
sr<-matrix(data=NA,ncol=256,nrow=256)
su
trunc(-1.5)
# [1] -1
floor(-1.5)
# [1] -2

Dear folks,
I have been struggling to create what I fondly imagined would be a
straightforward adaptation of the package's example to my own dataset, which
looks at incidence of depression following the birth of initial and up to 3
subsequent children (4 children in all, with all subjects having a

By the way, is there any difference between trunc() and floor()?
x <- c(1.05, 1.95, 2.5, 3.51)
trunc(x)

you could try something along these lines:
DF <- data.frame(V1 = c(0, 0.9, " ", 0.8, 0.1, 0),
V2 = c(0.9, " ", 0.8, 0.7, " ", 1))
DF
sapply(DF, function (x)
as.numeric(gsub("(^ +)|( +$)", "0", x)))
I hope it helps.
Best,
Dimitris

I'm not quite sure what you mean, but perhaps you want "floor()".
