If you can point me towards a doc that explains this in simple terms I
would be obliged. Don't expect you to have to provide the answer.
Any of the introductory texts should explain the various forms of indexing
and the use of the apply family of functions. They are both central to

Ouch! Hmmm. From the Value section of the apply docs... If each call
to FUN returns a vector of length n, then apply returns an array of
dimension c(n, dim(X)[MARGIN]) if n 1. Since I set MARGIN to 1, then I
was operating on rows where n is 3.
c(n, dim(X)[MARGIN])
[1] 3 2
How about
If you use emacs, then another alternative is Org-babel, which allows
you to mix and match languages. Using the literate programming
paradigm, Org-babel will tangle your hwriter code snippets and expand
references to any R-code that you want to embed within them.
I use Org-babel to combine
One way to do it:
1. Convert your date column to the Date class using the as.Date() function.
This allows you to do the necessary arithmetic on the dates below.
dt - as.Date(a[,4],%d/%m/%Y)
2. Create a factor out of your first three columns whose levels are in the
same order as the unique rows.
My group is working with datasets between 100 Mb and 1 GB in size, using
multiple log ins. From the documentation, it appears that vsize is limited
to 2^30-1, which tends to prove too restrictive for our use. When we drop
that restriction (set vsize = NA) we end up hanging the server, which
Dear Folks
I need to rotate PCA loadings and scores using R.
I have run a pca using princomp and I have rotated PCA results with varimax.
Using varimax R gives me back just rotated PC loadings without rotated PC
scores.
Does anybody know how I can obtain/calculate rotated PC scores with R?

I have been trying to write a function mv(a,b) to move an

exists for this side effect. Basically it just does
b - a; rm(a). With some checking and prompting about

The thing is, I'd like to be able to use either call by

I'm writing SQL queries, and it's very handy to be able to use sQuote for string
parameter values. It makes me wish that I could use an sQuote-like function for
enclosing column names and other identifiers in backticks, i.e., select `foo`
from `table`. Obviously I can do this with paste(), I'm
