Using the amazing package rayshader I wanted to render a video of my tour to Alpe d'Huez. Now I created an R package that can use any GPX file and return a 3D video animation from it. In July 2019 my friend Tjark and I went to France to cycle the 21 hairpin bends to Alpe d'Huez. The climb has...

I obviously haven't been blogging lately, but that doesn't mean that I haven't been thinking about what ought to be my next blog post. Fortunately, I've had the chance to get to know two particularly impressive R packages which are available to the scientific community through CRAN. Together, the two packages can be used to...
The aim of this blog post is to compute the implicit tax rates (ITR) on consumption, labour and corporate income for France, Italy, Spain, Germany and the Euro Area since 1995. We use as reference the report on Taxation trends in the European Union (2019) from the European Commission, and the previous reports since 2014. This database is built and updated...
Customer Relationship Management (CRM) is not only about acquiring new customers but especially about retaining existing ones. That is because acquisition is often much more expensive than retention. In this post, we learn how to analyze the reasons of customer churn (i.e. customers leaving the company). We do this with a very convenient point-and-click interface … Continue reading "Data...
Using a probability distribution to characterize uncertainty is at the core of statistical inference. So, it seems natural to try to summarize the information about the parameters in statistical models with probability distributions. R. A. Fisher thought so. In fact, he expended a great deal of effort over more than thirty years, and put his professional reputation on the...
It’s been a while since the last update, but RSiteCatalyst is still going strong! Thanks to Wen for submitting a fix/enhancement to enable the ability to use multiple columns from a Classification within the QueueDataWarehouse function. No other bug ...
by Virgilio Gómez Rubio Introduction In this session I will focus on Bayesian inference using the integrated nested Laplace approximation (INLA) method. As described in Rue et al. (2009), INLA can be used to estimate the posterior marginal distribution of Bayesian hierarchical models. This method is implemented in the INLA package available for the R programming language....
In May 2019 version 0.2.0 of tidync was approved by rOpenSci and accepted to CRAN. Here we provide a quick overview of the typical workflow with some pseudo-code for the main functions in tidync. This overview is enough to read if you just want to try out the package on your own data. The tidync package is focussed...
When it was floated that I should write this article, I approached it with trepidation. There is no better way to start an argument in the world of data than by trying to define what a Data Scientist is or isn’t – by adding in the complication of the relatively newly appearing role of Data engineer, there is no...
Hello All, November is the month of Thanksgiving, and vacations and of course deals galore! As part of saying thanks to my loyal readers, here are some deals specific to data science professionals and students, that you should definitely not miss on. Book deals: If you are exploring Data Science careers or preparing for interviews The post November Thanksgiving...
When we think of empathy in a career, we perhaps think of a nurse with a good bedside manner, or perhaps a particularly astute manager or HR professional. Data science is probably one of the last disciplines where empathy would seem to be important. However, this misconception is one that frequently leads to the failure of data science projects – a...
I’ve been struggling to get the {prophet} package to install on two RHEL 7 systems. Since I only have intermittent access to those systems I opted to use a local install of CentOS as a proxy environment. These instructions work for CentOS and should generalise to RHEL too. Setting Up the Environment The first thing that I needed to do was...
The newest version of {tvthemes} is now on CRAN! v1.1.0 features one new palette (Gravity Falls), vignettes, renamed functions, and a nice pkgdown website. install.packages("tvthemes") # v1.1.0 library(tvthemes) Gravity Falls ...
This post is just me amusing myself by exploring a tiny data set I have lying around. The dataset and the code is on Github. In 2014 (I think), I was teaching the introductory cell biology labs (pictures in the linked post) in Linköping. We were doing a series of simple preparations to look at
Using R and power analysis to inform experimental design A collaborator once asked me: “can you do that thing where you take a little bit of data and model it up to make lots more data?” Does it sound suspicious to fake a lot of data from a littl...
RBloggers|RBloggers-feedburner Intro: After developing the package RAthena, I stumbled quite accidentally into the R SDK for AWS paws. As RAthena utilises Python’s SDK boto3 I thought the development of another AWS Athena package couldn’t hurt. As mentioned in my previous blog the paws syntax is very similar to boto3 so alot of my RAthena code was very portable and this gave...
I recently did some pro bono work for Gun Control NZ reviewing the analysis by a market research firm of the survey that led to this media release: “Most New Zealanders back stronger gun laws”. The analysis all checked out ok. The task at that time...
The fifth release of the binb package just arrived on CRAN. binb regroups four rather nice themes for writing LaTeX Beamer presentations much more easily in (R)Markdown. As a teaser, a quick demo combining all four themes follows; documentation and e...
Introduction Imputing missing values is quite an important task, but in my experience, very often, it is performed using very simplistic approaches. The basic approach is to impute missing values for numerical features using the average of each feature, or using the mode for categorical features. There are better ways of imputing missing values, for instance by predicting the values using a regression model,...
This post is to announce that the latest update to AzureRMR is now available on CRAN. Version 2.3.0 brings several changes to make life easier when managing resources in Azure. New in this version is a facility for parallelising connections to Azure, using a pool of background processes. Some operations, such as downloading many small files or interacting with...
Recently, our team at Draper and Dash have been busy creating an NHS operational command centre. This command centre is different, as it uses a collection and ensemble of cutting edge predictive and machine learning techniques. To read the blog you can access this below: We have really enjoyed the process and we are in...
ATX GIS day is being held in Austin, TX on Nov 13 to celebrate the use of GIS (Geographic Information Systems) data!
Longitudinal changes in a population of interest are often heterogeneous and may be influenced by a combination of baseline factors. The longitudinal tree (that is, regression tree with longitudinal data) can be very helpful to identify and characterize the sub-groups with distinct longitudinal profile in a heterogenous population. This blog presents the capabilities of the … Continue reading LongCART...
The General Directorate for the Cadastre of Spain has spatial information of the all buildings except for the Basque Country and Navarra. This data set is part of the implementation of INSPIRE, the Space Information Infrastructure in Europe. More information can be found here. We will use the links (urls) in ATOM format, which is an RSS type for...
Introduction In my latest post I wrote about package GetEdgarData, which downloaded structured data from the SEC. I’ve been working on this project and soon realized that the available data at the SEC/DERA section is not complete. For example, all Q4 statements are missing. This seems to be the way all exchanges release the financial documents. I’ve found the same...
