Berlin satRday 2019

On 15th of June I’ve participated in satRdays here in Berlin. Specifically, I’ve suggested to have a workshop that I creatively named “Touring the tidyverse”. It was based on the 6 talks I gave over the last year at R users group (here is link to one of them). I’ve called it an “advanced” workshop since we’ve talked about topics that you normally don’t touch during workshops. However, I’ve decided to talk about them since there are plenty workshops that talk about these topics at introductory level, so there is a lack (from my point of view) of talks that go a little deeper into what is happening inside of tidyverse.

Touring the tidyverse: beyond tidyverse

In the final talk of the series I was looking bit beyond the tidyverse. Specifically, there are multiple package that don’t belong to the “core” tidyverse suite of packages, but still subscribe to tidy philosophy. In total, there are around 100 packages that satisfy this criteria. Obviously, it’s not possible to go over all of them, so to illustrate what I mean by “subscribing”, I’ve decided to highlight three packages: [Read More]

Touring the tidyverse: tidymodels

In the penultimate stop in “Touring the tidyverse” series of talks I was talking about tidymodels. It is a collection of packages that are built using tidy approach to make model fitting in R more predictable and extendable. The main force behind tidymodels-suite is Max Kuhn who you might know as an author and maintainer of caret package. tidymodels collection of packages is by far the least developed part of the tidyverse and it is under very active development at the moment.

Touring the tidyverse: tidyeval

Another stop on the journey through the tidyverse and this time it’s one of the most interesting and mysterious corners (I think) of the entire suite of tidyverse packages - tidy evaluation. My goal for the talk was to introduce ideas behind tidy evaluation in an interactive manner. To do that, I’ve used mostly exactly the same approach as Lionel Henry (main contributor to rlang that hosts tidy evaluation) outlined in this WIP book creatively called “Tidy evaluation”.

Touring the tidyverse: purrr

Another R meetup, another talk about tidyverse. This time I’ve talked about purrr. I really like this package, but I do have a feeling that I didn’t present in the best light possible. I certainly could have prepared a couple more examples that showcase why this package is so awesome and what kind of workflow it allows to create. To pat myself on the back a bit, it was a good idea to anticipate that it would take a bit longer than I’ve planned and to put “interesting” parts of purrr first. [Read More]

Touring the tidyverse: dplyr

On 25th of July, 2018, I’ve given a talk with the topic “Touring the tidyverse: dplyr”. It was a second installment of the series of talks about tidyverse. R markdown format of the presentation is here, code I’ve used during presentation is here. Over time I’m planning to cover most of the packages in tidyverse. Let me know if anything is not clear about this talk or any other in the series. [Read More]

Touring the tidyverse: tidyr

This Thursday I’ve given a talk at Berlin R-Users Group. The topic was “Touring the tidyverse: tidy data + tidyr”. The idea is that this will become a series of talks where each consequent talk is going to present one (or couple) of packages from the tidyverse. tidyr to me seems like a good choice for the first talk since concept of tidy data is so central to all of the packages.
