Like with most projects at Discindo, the OpenBudgetMKD application is based on R and {shiny}. It uses the {bs4Dash} and shinyWidgets for their excellent UI components, is packaged with{golem}, and will be available in Macedonian, Albanian, and English. From a programming perspective, the most interesting aspect for us was implementing internationalization using the {shiny.i18n} package and integrating this into a {golem}ized {shiny} application. These tools integrate seamlessly and make creating rather ... Read More

This week we were excited to take part in (and win!) an Open Data Hackathon organized by the Metamorfosis Foundation, a prominent NGO in North Macedonia whose mission and vision are to “… strengthen the awareness and capacity of citizens and civil society …”. The whole experience was very interesting, from the consultations with the organizers and advisers, to the presentations and the projects of the other participants. We were overall very proud to further contribute to the discussions about open data in North Macedonia. This is a topic ... Read More

Feed: R-bloggers. Author: П о д а т о ц и. I recently got acquainted with Windsor.ai – a hub for connecting various sources of marketing data like Facebook ads or Google Analytics. The platform is interesting because it provides ways to analyze and visualize your merged marketing data through template dashboards or to pipe the data to any number of tools (Python, R, Google data Studio, Tableau, etc). In collaboration with the people at Winsdor.ai, I developed a very simple package to interface with the Windsor.ai API. The new package, called windsoraiR, is available on CRAN and on Github ...

Feed: R-bloggers. Author: П о д а т о ц и. 2020 has been a sad and difficult year for many and certainly unusual for all of us. For us at Discindo, the adjustments required by limited mobility and closures were not easy, but our work is mostly online and remote anyway, so we are surely much better off than most. One of the activities we were involved this year was to contribute to an ongoing project that involved several in-person collaborative sessions and workshops with a broader audience. At the beginning of the year, the Free Software Macedonia NGO ... Read More

This week, I’m taking a break from our regular blog content to write about some of the nitty-gritty data science we do within RStudio. Specifically, I’m going to address a question I was asked soon after joining the blogging team: Which of your blog articles received the most views in the first ... Read More

Background A user on Stackoverflow recently asked a question about a program to generate Monte Carlo simulations on Bernoulli trials to calculate coverage percentages using Wald confidence intervals. One of the problems in the code is that probability value calculations are executed on individual observations rather than sums of successes and ... Read More

So it is time to present it. This package allows to get confidence intervals about the quantiles of any reasonable distribution (although the inference is based on a parametric model). The statistical inference is fiducial. To give an illustration, I’m taking a sample of ... Read More

As a package maintainer you might be observing an increasing number of questions raised by people that have recently migrated to R 4.0.0 and are now trying to get your package to work. Yet, rhub::check_with_rrelease() currently still uses R 3.6.3 as test ... Read More

Time sinks for data wrangling Estimating the time it will take to complete a project is an important part of being a successful PhD student, researcher or consultant. A major time sink on many analytical projects is data wrangling. Often the wrangling can take longer than the analysis. Here’s some good questions ... Read More

I really like generative art, or so-called algorithmic art. Basically, it means you take a pattern or a complex system of rules, and apply it to create something new following those patterns/rules. When I finished my PhD, I got a beautiful poster of where the k-nearest neighbors algorithms was ... Read More
