The CAPE R package implements a method, originally described in Carter et al. (2012), that infers directed interaction networks between genetic variants for predicting the inﬂuence of genetic perturbations on phenotypes. This method takes advantage of complementary information in partially pleiotropic genetic variants to resolve directional inﬂuences between variants that interact epistatically. CAPE can be applied to a variety of genetic variants, such as single nucleotide polymorphisms (SNPs), copy number variations (CNVs) or structural variations (SVs).
For detailed documentation about how to format data, load data, and analyze data, please see the CAPE vignette.
CAPE requires R 3.6+ to run.
# Install the released version from CRAN install.packages("cape") # Or the development version from GitHub # install.packages("devtools") devtools::install_github("TheJacksonLaboratory/cape")
CAPE provides demo scripts, which you can run to verify that the installation was successful.
