# I'd live to use the usual mathematical notations to do summatories and productories
# turns out, in Julia it's pretty easy as long as we keep things simple
# as we can just embellish the already defined sum() and prod() function
# only tweak is choosing a negative step if we want to sum from i = N to M with N>M

# for the summatory:
function ∑(f::T;from::Int, to::Int) where T <: Function
    step_sum = from > to ? 1 : -1
    sum(safer(f), range(from, stop = to, step = step_sum))

Diversity in Birth Canal across the world

A quick exploratory analysis of the dataset collected by BEtti and Manica (Betti L, Manica A (2018) Human variation in the shape of the birth canal is significant and geographically structured. Proceedings of the Royal Society B 285(1889): 20181807.)

We perform classic multidimensional scaling and contrast it with the aggregate means by Region and Population.

Let's load the tidyverse framework to wrangle data and plot it

In this course we will use:

- R as default programming language
  -  Tidyverse as the R dialect of choice

- The shell commands (bash or zsh), through the terminal
