Where or what is production? What does it mean when someone says to bring some data science product ‘in production’ ? What does it mean for data science products to be in production? Is your product already in production? Is it a magica...

In this walkthrough I modified a tutorial from the UbiOps cookbook ‘Python Scikit learn and UbiOps’, but I replaced everything python with R. So in stead of scikitlearn I’m using {tidymodels}, and where python uses a requirement.txt, I will use {renv}. So in a way I’m going ...

I was listening to episode 135 of ‘Not so standard deviations’ - Moderate confidence The hosts, Hilary and Roger talked about when to use tidymodels packages and when not. Here are my 2 cents for when I think it makes sense to use these packages and ...

I’ve been working with UbiOps lately, a service that runs your data science models as a service. They have recently started supporting R next to python! So let’s see if we can deploy a tidymodels model to UbiOps! I am not going to tell you a lot about ...

Last week I spend a few hours figuring out how to auto deploy a shiny app on 2 apps on shinyapps.io from github. You can see the result on this github repository. This github repository is connected to two shiny apps on shinyapps.io. Here is what I en...

In this post I will show how I run an R script on a schedule, by making use of ‘serverless’ computing service on the Microsoft Cloud called Azure Functions. In short I will use a custom docker container, install required software, install required r-packages using {renv} and deploy it in ...

I spend a lot of time yesterday on day 15 of advent of code (I’m three days behind I think). Advent of code is a nice way to practice your programming skills, and even though I think of myself as an advanced R programmer I learned something yest...

NETWORKS, PREDICT EDGES Can we predict if two nodes in the graph are connected or not? But let’s make it very practical: Let’s say you work in a social media company and your boss asks you to create a model to predict who will be friend...

In this tutorial I will show you how we go from network data to a rectangular format that is suited for machine learning. Many things in the world are graphs (networks). For instance: real-life friendships, business interactions, links between websites and (digital) social networks. I find graphs (the formal name ...

There are lots of rstats tutorials about creating beautiful plots, setting up shiny applications and even a few on setting up plumber APIs (but we could use more). However a lot of work consists of running a script without any interaction. This is an...

In this tutorial/howto I show you how to run a docker container on a schedule on gitlab. Docker containers are awesome because, once made, they run everywhere! It does not matter what type of computer^[Though I believe there is a problem with ARM bas...

In this tutorial I have an R script that runs every day on github actions. It creates a curve in ggplot2 and posts that picture to twitter. The use case is this: You have a script and it needs to run on a schedule (for instance every day). Other ways...

In this tutorial I have an R script that creates a plot and tweets it, it runs every day on gitlab runners. The use case is this: You have a script and it needs to run on a schedule (for instance every day). Other ways to schedule a script I ...

In this tutorial I have an R script that runs every day on heroku. It creates a curve in ggplot2 and posts that picture to twitter. The use case is this: You have a script and it needs to run on a schedule (for instance every day). In 2018 I wrote ...

So you want to compete in a kaggle competition with R and you want to use tidymodels. In this howto I show how you can use CatBoost with tidymodels. I give very terse descriptions of what the steps do, because I believe you read this post for implementation, not background ...

So you want to compete in a kaggle competition with R and you want to use tidymodels. In this howto I show how you can use lightgbm (LGBM) with tidymodels. I give very terse descriptions of what the steps do, because I believe you read this post for implementation, not ...
