This page collects released software packages.
The results in papers are generated by analysis scripts that are separate from released and carefully documented software packages. It may not be as pretty, or unit tested, or documented, but nonetheless, in an effort towards best reproducible research, we are trying to release the code supporting published results. Where available, these will be linked from the individual papers.
To install R packages directly from github, do, in R:
install.packages("devtools") library(devtools) install_github("chr1swallace/package.name")
New in v3.1 which is now up to date on CRAN:
finemap.abf() offers finemapping of single traits under a single causal variant assumption. See vignette for details.
github // extends SnpMatrix objects from the snpStats package by tying in sample and snp annotation data.frames. It allows the joint manipulation, and binding, of such objects, and includes a few functions I use for finding duplicate samples, applying QC, and aligning alleles between different datasets. It seems to work, and I intend to push it to CRAN in the future.
github // allows writing snpStats objects to disk in formats suitable for reading by snphap, phase, mach, IMPUTE, beagle, and (almost) anything else that expects a rectangular format.
CRAN // implements a Wilcoxon-based test for Gene Set Enrichment Analysis when testing regions of the genome according to GWAS derived evidence for SNP-trait association. For more detail, see the supplementary methods of (6).
github // implements an extension to the Weinberg method for testing for parent of origin effects to allow for multiple affected offspring in a nuclear family. I haven’t used it in a while, and it requires some checking just to get it to pass the CRAN tests. Unless I need to revisit it for another reason, I am unlikely to push it to CRAN, but it is a finished package. For more detail see:
