Bayesian Sparse Estimation of a Covariance Matrix.

bspcov

An R package for Bayesian Sparse Estimation of a Covariance Matrix

Building

To build the package from source, you need to have the following:

# lock the renv
pkgs <- c("...")
renv::snapshot(packages = pkgs)

# update docs
devtools::document()

## check package
VERSION=$(git describe --tags | sed 's/v//g')

## build manual
R CMD Rd2pdf --force --no-preview -o bspcov-manual.pdf .

## build package
sed -i '' "s/Version: [^\"]*/Version: ${VERSION}/g" "DESCRIPTION"
R CMD build .

Installation

You can install the development version of bspcov from GitHub with:

# install.packages("devtools")
devtools::install_github("statjs/bspcov", ref = "main")
