Overview

About

Maintained by Jason P. SinnwellCRAN page ↗Website ↗

The first stage is screening to detect rare variants in only cases. If the number of case-carriers of any rare variants exceeds a user-specified threshold, then additional cases and controls are genotyped for the detected variants and carrier status of these variants are compared for all cases and controls in the second stage. The package includes two main functions, trex for the exact test and optimalDesign to determine potential two-stage designs including an optimal design.

Install

R (source archive)

url <- "https://cran.r-project.org/src/contrib/Archive/trex/trex_0.5.tar.gz"
pkgFile <- "trex_0.5.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (0.5) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.
