Getting ready to attend rOpenSci unconf18 and probably working on tidyverse-like functions for the first time

It’s Friday 7pm and it’s been a long week with ups and downs1. But I’m enthused as I write this blog post. In less than a month from now I’ll be attending rOpenSci unconf18 and it’ll be my first time at this type of event. Yay! Building on my streak of good news, I'm delighted to have been selected to attend @rOpenSci #Unconf18 ^_^ Also, thanks to the and @LieberInstitute for their support!

Latin American R/BioConductor Developers Workshop 2018

Today I’m excited to invite you to attend the Latin American R/BioConductor Developers Workshop 2018! It’ll be held in Cuernavaca, Mexico from July 30th to August 3rd, 2018. You can find the official announcement in the Bioconductor support website. Let me share with you why I’m excited about this workshop. At BioC2017, Alejandro Reyes and I talked for a while about the low representation of Latin Americans through out the years that either of us have attended the BioC meetings1.

blogdown archetype (template)

In a recent blog post I wrote about having a template for blogdown posts. I wanted to know if it was possible to do this and make my life (and others hopefully) easier for writing new blog posts that are ready to go with the features I frequently re-use. In my case, I like using BiocStyle (Oleś, Morgan, and Huber, 2017) for functions such as CRANpkg(), Biocpkg() and Githubpkg(). I also like using knitcitations (Boettiger, 2017) for citing with citep() packages or papers; I use citation() and bib_metadata() to get the necessary information, respectively.

blogdown Insert Image addin

Have you ever tried inserting an image into a blogdown post? Maybe you have, or maybe you tried and gave up. Lets first review the hard way before getting to the solution I contributed. The hard way The process involves copying the target image to the static directory that corresponds to the blogdown post. Lets say that your post is called 2018-03-07-my-new-post.Rmd and lives at content/post/, so it’s full path is content/post/2018-03-07-my-new-post.

R markdown blog template

This blog post is mostly for myself but maybe it’s useful to others. It contains my current R markdown blog template. I initially posted this as a question at StackOverflow. Then I read how much a burden we put in Yihui Xie and decided that my current setup (copy-pasting) works just fine. In any case using blogdown with the RStudio IDE is much simpler than what I used to do in the past with jekyll or with even my prior setup with blogdown.

Updating R

As you might know by now, the latest R version was recently released (R 3.4.0). That means that you are highly encouraged to update your R installation. There are several ways to do this some of which are documented in these other blog posts: Tal Galili, 2013, Kris Eberwein, 2015. You would think that it's just a matter of downloading the latest R installer for your OS, installing it, and continuing your analysis.

How to ask for help for Bioconductor packages

tl;dr Please post your question at the Bioconductor support website and check the posting guide It's important that you provide reproducible code and information about your R session. Recently I have been getting more questions about several packages I maintain. It's great to see more interest from users, but at the same time most questions lack the information I need to help the users. I have also gotten most of the questions via email, which is why I am writing this post.

Easily explore a table with shinycsv

Have you ever had to explore a table with data? I believe the answer is yes for most people that work at a computer or even just use it for communicating with their friends and family. Tables of data pop up everywhere, for example in personal finance. Websites like allow you to download your transactions in a CSV file called transactions.csv. CSV is one of the many formats for storing tables and most likely when you try to open the transactions.

Finding possible class schedules

Over the weekend my brother wanted to figure out his class schedule for the next semester. He is a veterinary medicine and zootechnology student at UNAM. For this upcoming semester there is a set of classes he has to take and each has 8 or so instructor options. The website where he finds the class times lists about 8 pre-constructed class schedules. So he normally finds one he likes quite a bit, and then manually starts checking if he can change X instructor for Y for a given class.

Are you doing parallel computations in R? Then use BiocParallel

It's the morning of the first day of oral conferences at #ENAR2016. I feel like I have a spidey sense since I woke up 3 min after an email from Jeff Leek; just a funny coincidence. Anyhow, I promised Valerie Obenchain at #Bioc2014 that I would write a post about one of my favorite Bioconductor packages: BiocParallel (Morgan, Obenchain, Lang, and Thompson, 2016). By now it's on the top 5% of downloaded Bioconductor packages, so many people know about it or are unaware that their favorite package uses it behind the scenes.
