I am a bioinformatician currently doing a PhD at the IBD lab of Dr. Julian Panès under the joint supervision of Azucena Salas and Juanjo Lozano. My research interests include data integration (my PhD topic) and functional enrichment.
Other interest are helping with data to make better decisions and improve processes, from transparency, lawyer activities, media handling to open source activities. To be more effective at this I’m in touch with some organizations and I created some packages deposited in Bioconductor, CRAN, rOpenSci, rOpenSpain and GitHub.
Outside programming I enjoy hiking, jumping rope and diabolo as hobbies.

Upgrading rtweet to 1.0.2

In this post I will provide some examples of what has changed between rtweet 0.7.0 and rtweet 1.0.2. I hope both the changes and this guide will help all users.

Leadership in open source projects

This is the second part of the previous post about concepts around open source/free software. Since last book, I also read Uncurled which recommended “The Making and maintenance of open source software” (I will short it to MMOSS) and “Producing Open Source Software” (POSS), which provide first hand experiences about how those maintainers handled different projects.

Concepts around open source/free software

This post is to lay out some concepts I picked up after reading “The Making and maintenance of open source software”. Having these concepts in mind might help me on my contributions to R and OSS in general.

Improving (analysis) process: developing packages

I was invited to give this talk shortly after my talk at useR!2021. I was very nervous because I would like to have such a community on Spain and work together with them.

Workshop: Creating packages

I was invited by Francis Mensha on R-devel slack to give this workshop on April 29th for the R User Group Ghana. First time teaching R stats and remote I expected people to follow the workshop and run the code and then ask questions but I was asked to do it myself.
