I want to see, how sctest of the strucchange package is implemented.
I install and load the package:
install.packages("strucchange")
library(strucchange)
Now I want to look at the implementation and I do:
sctest
But this gives only
> sctest
function (x, ...)
{
UseMethod("sctest")
}
<environment: namespace:strucchange>
So I tried getAnywhere(sctest)
, but this does also not help me. So how can I look at the code?
I looked at Looking at internal Methods and the R Inferno.
EDIT: I tried
methods(sctest)
this gives me
[1] sctest.efp* sctest.formula* sctest.Fstats* sctest.gefp*
Non-visible functions are asterisked
Now I can use getAnywhere() but which of these functions is the right one for me?
