optim() argument scoping: passing parameter values into user's subfunction
...within its evaluation. This
function allows for the parameters to enter as arguments to various
probability distribution functions.
However, I am violating some scoping convention, as somewhere within the
hierarchy of calls a variable is not visible. I will give a genericized
example here.
> myFxn <- function(parms, Y, phi, <other args>) {<body of function>}
### I want to optimize this over its first argument
> optim(par=<numeric(>2)>, fn=myFxn, ### end of named args, next are
all in "..."
Y=<data>, <other args>,...
