It really depends (which was one of the points of my earlier post 
about how broad this field is). For someone doing academic 
research or statistical analysis for, say, marketing purposes, 
the interactive code they write is the production code. They're 
not going to write two versions of their code. I know for web 
applications or finance or some other areas where the distinction 

But as far as telling people "don't write code in R", that's 
simply a non-starter, and there's no reason to even begin a 
project like this if you're going to tell people to avoid 
existing libraries in either R or Python. They'll just shrug when 
you start talking about performance because for the vast majority 
of what they're doing it's not an issue.
