I was recently contacted by the Stanford Deep Data Research Center at Stanford School of Medicine where they are working on "pioneering a transformative approach to precision medicine research and education." The center is led by Amir Bahmani who has made it his mission to make it possible for anyone to learn about bioinformatics and…
I just paid for another two years of web hosting for 324 USD (13.5 USD per month). I upgraded my account from a Business account (7.5 USD per month) to a Business II account, which is the same package but with a bit more storage. I upgraded my account because I decided I’m going to…
I recently found out that when install.packages() fails, it only returns a warning and not an error, i.e., the exit code is 0. R -q -e 'install.packages("thisdoesnotexist!!!")' > install.packages("thisdoesnotexist!!!") Installing package into ‘/home/dtang/R/x86_64-pc-linux-gnu-library/4.3’ (as ‘lib’ is unspecified) Warning message: package ‘thisdoesnotexist!!!’ is not available for this version of R A version of this package for…
A quick post on testing Singularity builds, where I discovered how the %test section of the Singularity Definition File works. If you aren’t familiar, the Definition File is similar to the Dockerfile for Docker; it is used to define and build the image. From the documentation: A SingularityCE Definition File (or “def file” for short)…
For running RStudio Server in a container, I’ve written about how to run RStudio Server with Docker; in the post I also listed out some reasons why you would want to do that instead of simply installing RStudio on your computer. This post demonstrates one way of running RStudio Server with Singularity. I learned that…
Recently I have been learning about Singularity and have been experimenting with building Singularity images. However it seems that there is no layering in Singularity, which exists with Docker and Dockerfiles. This is quite convenient to have because building will resume from the point where the last step failed. However the comment: You can build…
ffq is a tool that can be used to fetch metadata from several data repositories. It can also be used to generate links to raw data hosted at the EBI (via FTP), AWS, GCP, and NCBI. I wrote a short Bash script called ffs that can generate the commands needed to download the raw data…
Last updated: 2023/07/28 I recently learned about code snippets in RStudio (ignore the strikethrough). As the name suggests, they are snippets of code that you can quickly insert into your source code in the source pane of RStudio. There are two ways to add code snippets: Click on the following: Tools -> Global Options ->…
I use tidyverse packages a lot and most of the times I prefer them over base R functions, especially when it comes to plotting. However, sometimes I want to write an R script with no dependencies. This is typically referred to as using base R, i.e. using only functions that come with R. Theoretically this…
