Well, Rui -- I'll bet that that gobSmacked him (and probably others)!
So here's just a tiny extra effort at enlightenment.
The keys are understanding that:
1. Matrices are (formally) just 2-d arrays.
2. All arrays are just vectors, indexed in "column major" order --
i.e. rows vary the fastest, th

Hello,
You don't need the loop, it can be done with one much simpler instruction.
Since the number of rows is not important, the example uses a 10x603 matrix.
x <- matrix(seq_len(10*603), ncol = 603)
y <- array(x, dim = c(10, 3, 201)) # that's it
# See the first two
y[, , 1:2]
Hope this helps
Hello,
Try the following.
Q_use_2 <- split(Q_use, as.Date(Q_use$date))
SC_use_2 <- split(SC_use, as.Date(SC_use$date))
lapply(seq_along(Q_use_2), function(i) cor(Q_use_2[[i]]$Q,
SC_use_2[[i]]$SC))
Hope this helps,

It sounds like a local system problem. Are you running on a local intranet or
have something cpu intenstive running in the background?

Hi Dave,
You need to save the ff file before you quit R.
As in ffsave(ffcolTest, file = \\ffTest')
When you reopen R, you can now use ffload("").
Regarding your question on if ff suits your needs. This is probably the
case, I'm regularly using it for data size a lot bigger than yours.
Remark that

You should probably address this to RStudio (which is an independent
commercial entity) directly: http://support.rstudio.org/
I've found them wonderfully responsive and capable, so I'm sure
they'll be able to sort you out.

Hi,
The combination of ipad+rstudio (server) would be a fantastic combination-if

Use sample.
Like this for example

Hi all,
I am wondering if do exist a function in R that allow me to sample or

L.S.
We would like to generate fractional design for a conjoint analysis. For
example we would like to reduce 2x2x2x2x3 --> 12-16 profiles. We tried the
R-package "conjoint" and we found an article which describes how to make
fractional design for these kinds of studies with Algdesign:

I am using R dixon.test in order to perform Q test for detection of outliers.
The p-values for high Q values are consistent with the table in Rorabacher,

small Q-values get problematic p-values. For example:
