How to call to R_KalmanLike from outside StructTS
Dear all:
I want to modify the 'StructTS' function from the 'stats' package. First, I am writing a working copy of the original version and got some problems.
I have two versions of the function plus the original one. The first version is the same code as the 'StructTS' function:
StructTS.v1 <- function (x, type = c("level", "trend",
