Hi:

this with, but is it possible that theta is meant to be a parameter
*vector*? If so, then you should have
eta <- theta[1]
K <- theta[2]
The code theta[, 1] means that you want to extract the first column of the
_mat
Hi,
Please check your dimensions of theta.
> ff <- function(theta) theta[,1]
> theta <- 1:5
> ff(theta)
Error in theta[, 1] : incorrect number of dimensions
> theta <- data.frame(c(1:5),c(6:10))
> ff(theta)
