Course Prerequisites
Install R 4.4.x from CRAN then install the following R packages:
## For installing Bioconductor packages
if (!requireNamespace("BiocManager", quietly = TRUE)) {
install.packages("BiocManager")
}
## Install required packages
BiocManager::install(
c(
"usethis", ## Utilities
"here",
"biocthis",
"lobstr",
"postcards",
"sessioninfo",
"SummarizedExperiment", ## Main containers / vis
"iSEE",
"edgeR", ## RNA-seq
"ExploreModelMatrix",
"limma",
"recount3",
"pheatmap", ## Visualization
"ggplot2",
"patchwork",
"RColorBrewer",
"ComplexHeatmap",
"spatialLIBD" ## Advanced
)
)You will also need to install RStudio version RStudio 2024.12.0 or newer.
Course Evaluation
- Participation
- (main evidence) written and/or verbal participation during class
- This is tracked by day by the TA. Each day counts as a category.
- (optional, strongly encouraged for your own career) Community building: CDSB Slack (introduce yourself), Bluesky, GitHub, etc. These are tracked by the TA: please let the TA know of your participations.
- GitHub issues on the course repository
- CDSB Slack #bienvenida channel
- Bioconductor Slack #introductions channel
- Bluesky posts related to the course
- Grading:
- 0%: no participation
- 25%: participation in only 1 out of 8 categories (4 days, 4 public participation categories)
- 50%: participation in 2 out of 8 categories
- 75%: participation in 3 out of 8 categories
- 100%: participation in 4 or more categories
- (main evidence) written and/or verbal participation during class
- Public work
- (main evidence) Taking notes on your GitHub class notes repositories
- (optional) Deploy an iSEE
shinyapp on shinyapps.io - (advanced and optional) R package with notes following
usethis::create_package()+biocthis::use_bioc_pkg_templates().
- Final project
- (main evidence) code in a public GitHub repository (different from the notes one) following the structure from LieberInstitute/template_project
- (optional) a rendered Rmd file (RPubs, GitHub, etc) on a public URL
- (optional advanced) Copy this repository, remove all the Rmds except the index.Rmd and edit accordingly. GitHub Actions will then help you render it. You’ll need to fetch the
gh-pagesbranch and at least make one commit for the HTML to be available such as this commit. You might also run into this GitHub default permission setting that you’ll need to change.
The final grade will be a weighted average from the evaluation by the TA (20%), your public work (40%) and your final project (40%).
Projects, public work and notes are due at 9 am US Eastern on Monday February 10th, though we recommend doing any work related to this course by Friday February 7th.
