Function definition vector default parameter

[alxsimon]

Hi, more of an Eidos coding question.

I don't seem to be able to use a vector (of floats in this case) as an optional parameter with defaults.

I don't know if it's just not possible in Eidos or just me coding this wrongly.

e.g.:

function (void)myfunction(object<Dictionary>$ model, [float x_bounds=c(0.0, 1.0)]) {
    ...
}

My issue is with the second parameter x_bounds.
The error I get is this:
ERROR (EidosScript::Match): unexpected token '(' in parameter specifier; expected ']'.

Thanks!
Alexis

Hi! Yes, this is something you can do in R but not in Eidos. Default values have to be simple constants; they cannot involve calculations. So a call to c() is not allowed; even something like 5+5 is not allowed. Typically in this situation I make NULL be the default value for the parameter, and then check in the function's script for a NULL value and replace it with the desired default. Not great, but it works.

I see, thanks for the trick!
