[R] creat contingency tables with fixed row and column margins

Hi all, Is there an R function that can be used to enumerate all the contingency tables with fixed row and column margins. For example, can we list all 3 by 3 tables with row margins 3,6,6 and column margins 5,5,5. Thanks very much! Hanna [[alternative HTML version deleted]]

[R] Need Help To Solve An Equation In R

Dear Sir/Ma'am, I am trying to make a function to solve an equation that is given below: findH <- function(p_star, k){ fun <- function(y){ (pnorm(y+h))^(k-1)*dnorm(y) } lhs <- integrate(fun, -Inf, Inf)$value return(uniroot(lhs, lower = -10, upper = 10, tol = p_star)$root) } In lhs, I integrated a

Re: [R] Problem with Example with Lattice

I was surprised this worked at all, as I usually use the formula interface. Anyway, you need to explicitly specify the point types via the pch argument. The default uses trellis.par.get("dot.symbol"), which is just a single value. -- Bert Bert Gunter "The trouble with having an open mind

[R] Problem with Example with Lattice

Dear All, I am making my baby steps with the lattice graphic system. I am going through the great book by Sarkar which provides plenty of examples. However, I notice that some of them appear to give a different result on my system. For instance, consider the following library(lattice)
