Fork Star Watch Download I love Nottingham Forest and have been trying to find a way to include them in one of my tutorials, as they are in the play-offs to go into the top flight leagues. This tutorial allows you to download images from Selenium and automate Google Chrome. Can I get a live tutorial? The live tutorial is here: Creating the bones of the project The first stage would be to define the dependencies: Downloading the web driver The next step would be to download the ChromeDriver for your ...

Through sitting in lectures and webinars and package development tutorials I thought perhaps I should make some of my code, that was sitting there in a dusty private GitHub repo, open and accessible to all. This started me on the journey to develop R packages. OddsPlotty – the first package I created The first package I created was called OddsPlotty and I created this as a way to easily explain the ...

This is a great effort and is crammed full of functions for working with population health datasets, standardised rates, standard visuals, etc. It contains a smorgasbord of delightful functions to wet any R developers appetite. About the package SangerTools was born out of necessity. It is the formal aggregation of a set of coding solutions employed regularly to carry out Population Health Management Analytics; rapidly and consistently. It has has been created specifically for ... Read More

This time it is a collection of datasets aimed at giving people in healthcare, and beyond, some solid examples for using with R. There remains a few excellent packages for this, such as mlbench, but they are limited in the number of datasets you can derive. Using the package To use the package I have compiled a YouTube video to show you how the datasets could be used, with a thorough example in TidyModels of how to implement the thyroid disease dataset ...

The NHS-R Virtual Conference concluded this week and we have had a number of excellent speakers from the Health & Social Care sector, alongside working with key partners of interest. It kicked off with a full day jammed packed of speakers from all over the NHS. The second day we had international speakers from the US, Australia and other European countries. The keynotes this year were provided by Professor Frank Harrell who did an excellent talk on “statistical mistakes to avoid” and Julia Silge @RStudio discussing “Preparing and processing text for Machine Learning”. I was ... Read More

Their argument is that TidyModels is new and shiny and we should be using the most up to date tools. I get this justification, but is caret really dead? My answer is “not by a long shot!“. Hats off to Max Kuhn and the team for rolling out these awesome packages and without Max, modelling in R would not be as easy and fun. How they stack up? This is not really a fair comparison, as CARET is ... Read More

This has arisen as part of a workshop the NHS-R community are doing around R in Production: show and tell, but instead of just making it local, I thought I would open up my part of the tutorial to everyone. The process follows this generic process for ML model deployment: The first tutorial focuses on the training component and model building. The second tutorial focuses on Deployment via Docker and the third tutorial is the ... Read More

DISCLAIMER I am a data scientist and have made all these mistakes, but I have had the privilege of sitting on the managerial, project lead and developer side of the fence, and here are some tips to getting your stakeholders (i.e. anyone involved in the project team or has an interest in the success of the project) on board and delivering a successful data science project. #1 Technical Language is a no no Often when I have managed data scientists, and have been a data scientist, I have seen statisticians being too technical about their ...
