Just wanted to acknowledge Hannah who has been demonstrating for maybe 3 years with me now. She is knowledgeable, intelligent, confident, creative and in this case teaching some stuff on R to the Msc students – yes because she can do stuff I can’t. And this is Liam too, he is starting his PhD so I’m hoping he can fill Hannah’s boots when she completes. I reckon, judging by his few sessions this year, he will be able to.
