It depends: A dialog about dependencies by Jim Hester

Basement Theatre of Crown Centre 1 Building 5005 Rockside Road , Independence, OH 44131 (map)

Software dependencies can often be a double edged sword. On one hand they

let you take advantage of others' work, giving your software marvelous new

features and reducing bugs. On the other hand they can change, causing your

software to break unexpectedly and increasing your maintenance burden. These

problems occur everywhere, in R scripts, R packages, Shiny applications and

deployed ML pipelines.

So when should you take a dependency and when should you avoid them?

Well, it depends!

This talk will show ways to weigh the pros and cons of a given dependency and

provide tools for calculating the weights for your project. It will also

provide strategies for dealing with dependency changes, and if

needed, removing them. We will demonstrate these techniques with some real life

cases from packages in the tidyverse and r-lib.
