create a pairwise coocurrence matrix
Hi all,
I am trying to construct a pairwise coocurrence matrix for certain terms
appearing in a number of documents. For example I have the following table
with binary values showing the presence or absence of a certain term in a
document:
term1 term2 term3 term4 term5 doc1 1 1 0 0 1 doc2 1 1 0 1 1 doc3 1 0 0
0 1
And I want to have a matrix with the number of the pairwise coocurrencies.
So,

strange strsplit gsub problem 0 is this a bug or a string length limitation?
I was working with the rmetrics portfolioBacktesting function and dug into
the code to try to find why my formula with 113 items, i.e. A1 thru A113,
was being truncated and I only get 85 items, not 113.
Is it due to a string length limitation in R or is it a bug in the strsplit
or gsub functions, or in my string?
I'd very much appreciate any suggestions

Dirichlet surface
Dear list members,
I want to draw surfaces of Dirichlet distributions with different
parameter settings.
My code is the following:
#<begin code>
a1 <- a2 <- a3 <- 2
#a2 <- .5
#a3 <- .5
x1 <- x2 <- seq(0.01, .99, by=.01)
f <- function(x1, x2){
term1 <- gamma(a1+a2+a3)/(gamma(a1)*gamma(a2)*gamma(a3))
term2 <- x1^(a1-1)*x2^(a2-1)*(1-x1-x2)^(a3-1)

Bug in as.character? (PR#14206)
A long formula which is converted using as.character, looses its last

Shorter formula is ok though.

slider control questions
DeaR UseRs,
I have the following code (see below).
It is working as expected although I have two problems/questions:
- how can I set the size of the graph? It may sound silly, but I couldnt figure that out
- is it possible to export this small "interactive aplication" to html or a latex document, or maybe pdf?
Thank you for your attentions.
Best wishes:

How to get all possible combinations?
Dear all, suppose I have a vector with elements as:
Vec <- c(2,3,4,5,6)
Now I want to have all possible combination of length 3 using those
elements and without any repetition. Like, I want to have 1
possibility like 2-3-4 but not 3-2-4.
Can somebody guide me how to achieve that in R?
Thanks for your help.

For the most part the students will be using R for analysis. The problem is
there will be some simple differential equations for the students to solve.

Integrate() error message, I am at a loss
Hello!
I have a problem with integrate() in my function nctspa(). Integrate
produces an error message "evaluation of function gave a result of
wrong length". I don't know what that means. Could anyone suggest me
what is wrong with my function?
These are the examples of function calls that work OK:

question on nbdkit shutdown behavior
I'm observing a difference in timing on nbdkit shutdown that is
dependent on client behavior, and I wonder if that's a bug, but I can't
figure out where to patch it.
When there is no connection present, sending SIGINT to nbdkit terminates
immediately.
If, on the other hand, there is a single client currently connected, the
termination behavior on SIGINT depends on what the client has
