It’s been a while since my last blog post. Indeed, my free time is used to improve packages like “{fusen}: Inflate your package from a simple flat Rmd” , “{attachment}: Tools to deal with dependencies in scripts, Rmd and packages” or “{gitlabr}: An R client for the GitLab API”. Hence, drawing some …

#30DayMapChallenge: 30 days building maps (3) - Earth is spherical
The #30DayMapChallenge was initiated by Topi Tjukanov on Twitter. This is open to anyone who would like to show a map, whatever the software is. In this blog post, I will show maps made with R. I add constraints to myself for fun. This week, I will create maps that remind map makers that Earth is …

Follow moving particle trajectory over raster with {rayshader}
{rayshader} is a fantastic package for 3D mapping, but it comes with the limitations of {rgl}. I always found it a shame not being able to travel in all directions over my 3D objects. In this blog post, I will show a trick to simulate particle trajectory in 3 dimensions like in a “first person” …
Create a twitter bot on a Raspberry Pi 3 using R
With Marion Louveaux, we decided that we had to build a Twitter bot for our preferred hashtag. We explored different possibilities but truth is I couldn’t resist building it using R and {rtweet}. Here are the steps I used to set up a Twitter bot on my Raspberry Pi. […] I use package {rtweet} …
Render mesh3d objects with rayshader and rayrender
People like to show 3D images in their presentations because it usually impresses the audience. Does it really ? I do not care ! I am just looking for an opportunity to play with some 3D images… This blog post is a detailed version of some 3D images shown during my presentation “Everything but maps …
Play with spatial tools on 3D cells images
Let’s play with mapping tools on non-maps data ! {rayshader} is nice on raster maps, but what about using it on segmentized plant cell? […] I wanted to find a good reason to play with Tyler Morgan-Wall packages for 3D visualisation of raster data: {rayshader} and {rayfocus}. Using cell …
Rshiny expert image comparison app
The expert image comparison was long: 40min for the small analysis and 3h for the complete one. As the shinyapp is freely hosted on the Rstudio shinyapps.io servers, it was not possible to save outputs of a specific session on the server. Thus, the web application has been built such that the …
