This reproducible R Markdown analysis was created with workflowr (version 1.6.2). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.

R Markdown file: up-to-date

Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.

Repository version: 7fd8e1c

Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.

The results in this page were generated with repository version 7fd8e1c. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.

Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish or wflow_git_commit). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:

Note that any generated files, e.g. HTML, png, CSS, etc., are not included in this status report because it is ok for generated content to have uncommitted changes.

These are the previous versions of the repository in which changes were made to the R Markdown (analysis/index.Rmd) and HTML (docs/index.html) files.

Gene set testing for methylation arrays

This site contains the development and evaluation of various methylation array gene set testing methods available in the Bioconductor missMethyl package. Follow the links below to explore the different parts of the project.

Analysis

  1. Explore EPIC array bias
    • Explore the various array biases on the EPIC array that affect gene set testing.
  2. Explore 450k array bias
    • Explore the various array biases on the 450k array that affect gene set testing.
  3. Generate a blood cell RNAseq "truth" set
    • Analyse an RNAseq sorted blood cell dataset and identify the top ranked gene sets for each cell type comparison.
  4. Compare FDR of different methods
    • Analyse the normal samples from a 450k array KIRC TCGA dataset using various genset testing methods to estimate their false discovery rate control.
