Are you a Microsoft Windows R user? Does your Windows username include a space? Like Firstname Lastname. Then you might occassionally run into issues installing packages due to spaces. Solutions You could either re-install Windows with a username that has no spaces such as Lastname 1, but that’s probably not an easy option. Or you can: Edit your TMP and TEMP environment variables to a location with no spaces, like C:\TEMP following instructions like these ones.

The hugo-academic theme which powers my website is active and frequently updated. I don’t update my website that frequently anymore, but I recently found about many of their changes when I made the CDSB website. We are delighted to share with you our new webpage at with both English and Spanish support Estamos encantados de compartirles nuestra nueva página web que viene en español e inglés It'll replace/remplazará a https://t.

These past months I’ve been mostly working on one huge project which might be close to an end, hopefully! This project involves a massive manuscript with many supplementary figures and tables. Today we sent it out to other members in our team, and to celebrate, I’m now writing more 😅: though this is a blog post. I’m allowing myself to do so before I dive into the pile of tasks I haven’t completed1.

This blog post was first published at the CDSBMexico website. #CDSBMexico: remember to apply for BioC2019 travel scholarships!! Due date is March 15th Let us help you! Here we give you some ideas 💡We can also give you feedback via Slack ✅#rstats #bioconductor @Bioconductor #bioc2019 #diversity #LatAm #rstatsES — ComunidadBioInfo (@CDSBMexico) March 1, 2019 About 10 months ago we announced our plans to start a new community of R/Bioconductor developers in Mexico and Latin America.

In the past months I’ve had a recurrent conversation with many people. This conversation is typically started with the question: why do you like living where you live? Some of them might be considering moving to the city I live in for work, some of them are thinking about leaving, some are happy here. Ultimately, everyone is different and what makes some happy might not be for the rest. Some friends want to live in larger cities, others want different climates, others want to move in with their long distance relationship partners, etc.

While working at Winter Genomics I taught two courses for students of the Biomedical Sciences PhD Program (PDCB) from the National Autonomous University of Mexico (UNAM).

  1. Analysis of High-Throughput Sequencing data with Bioconductor Aug-Dec 2010.
  2. Introduction to R and Biostatistics (along with two other teachers).


While I was at the Institute of Biotechnology (UNAM) working with the Winter Genomics crew I organized two courses. One was a series of various bioinformatics and biology mini-courses and another one involved members of different institutions.

  1. Introduction to R for bench biologists Oct-Nov 2009. This mini-course has quite a bit of material on learning how to make plots with R.
  2. Métodos Estadísticos y Analíticos de Datos Genómicos (Statistical Methods and Analysis of Genomic Data) Jan 2010. This one week course had lectures about Perl, using a Cluster, high-throughput technologies, R and Bioconductor, C, and biology overviews.


I taught three courses during my undergrad stage at the Undergraduate Program on Genomic Sciences (LCG). Each of these courses has its own website organizing the material. These are:

  1. Intensive course on R/Bioconductor Oct-Nov 2008 (backup)
  2. Principles of Statistics Feb-June 2009 (backup)
  3. Seminar III: R/Bioconductor Aug-Dec 2009 (backup)
