A problem with using the "outer" function
..." to work on one of my functions. Here is a simple example illustrating my problem: > b1 <- c(1.2,2.3) > b2 <- c(0.5,0.6) > x <- c(3e+01, 1e+02, 3e+02, 5e+02, 1e+03, 1e+04, 1e+05, 1e+06) > y <- c(2,4,2,5,2,3,1,1) > n <- c(5,8,3,6,2,3,1,1) > outer(b1,b2,FUN=bpllkd,x,y,n) [,1] [,2] [1,] 17.78031 17.78031 [2,] 17.78031 17.78031 These values should all be different. What is the problem here? The function "bpllkd" is given below: thanks for any help, Ravi. > bpllkd function(t1,t2,x,y,n){ p <- 1 - (1+x/10^t1)^(-t2) keep <- !((p...

How top print intermediate values from inside a function?
...e, how do I get it to print the intermediate variable "mh.new" for each simulation, when I call the function "MHsim.ind"? thanks for any help, Ravi. #################################################################### MHsim.ind <- function(nsim=1000,start=0,spread=1,likfn=bpllkd){ # Independence Metropolis algorithm with candidate density a #multivariate Student t-distribution with 1 degree of freedom, whose #mean and variance are taken to be MLE and its covariance matrix mh.0 <- start npar <- length(start) mh.sim <- matrix(0,nrow=nsim,ncol=npar) i <- 0 whi...
