Practically, one would not need this extension unless\ninterested in applying `eigvaldisp::Var.VRR()` to large correlation\nmatrices (p \u003e 100 or so).\n\n\n## Installation\n```\n# install.packages(\"devtools\")\ndevtools::install_github(\"watanabe-j/eigvaldispRcpp\")\n```\n\nThis package has the following dependencies:\n```\nDepends: eigvaldisp\nImports: Rcpp, RcppParallel\nLinkingTo: Rcpp, RcppArmadillo, RcppEigen, RcppParallel\nSuggests: testthat (\u003e= 3.0.0)\nSystemRequirements: GNU make\n```\n\nIn case you are unfamiliar with `Rcpp`, it requires a working C++ compiler.\nMost Linux and macOS users would already have one. Windows users will require\n[Rtools](https://cran.r-project.org/bin/windows/Rtools/),\nwhich comes with GNU `make`.\nSee http://www.rcpp.org/ or https://cran.r-project.org/package=Rcpp for details.\n\n\n## See also\nWatanabe, J.
