How we did it

So it really wasn’t that hard. We held the questionnaire on typeform. Conveniently, my colleague has created a package rtypeform which is an interface to the typeform API. You can install this from CRAN in the usual way

install.packages("rtypeform")
library("rtypeform")

The following code will give you a data frame called q containing a column for each question contained in the WhyR questionnaire.

typeforms = get_all_typeforms()$content
uid = typeforms[typeforms$name == "WhyR", "uid"]
q = get_questionnaire(uid)$completed

Now, obviously, we can’t give you access to this so I’ve hidden the Jumping Rivers API key. But, given you have your own API key assigned to the variable typeform_api this code will work (remember to change the questionnaire name!). With that, a bit of dplyr and the classic sample(), we can generate a winner for the competition

The winners

Drum roll please… the winner is…

Agnieszka Fronczyk!

Congratulations Agnieszka! We’ll see you in Wroclaw!

Commiserations to all our unlucky participants. However, we are sponsoring more data science events to come so keep an eye out here for more competitions!
