String parameters?

Should I be able to do

rcp::String = Parameter()

where I set the rcp parameter to, say, “rcp85”?

I don’t get any error when I create the model or set the parameter, but when I then run the model, I get this:

Looks like a bug to me? I don’t see why we wouldn’t want this to work.

Okay, I’ll open an issue.

@jrising @davidanthoff I can take a look at this this weekend

@jrising this is fixed here: and will be merged as soon as I get approval
