rrcov
: Scalable Robust Estimators with High Breakdown PointThe package rrcov
provides scalable robust estimators with high breakdown point and covers a large number of robustified multivariate analysis methods, starting with robust estimators for the multivariate location and covariance matrix (MCD, MVE, S, MM, SD), the deterministic versions of MCD, S and MM estimates and regularized versions (MRCD) for high dimensions. These estimators are used to conduct robust principal components analysis (PcaCov()
), linear and quadratic discriminant analysis (Linda()
, Qda()
), MANOVA. Projection pursuit algorithms for PCA to be applied in high dimensions are also available (PcaHubert()
, PcaGrid()
and PcaProj()
).
The rrcov
package is on CRAN (The Comprehensive R Archive Network) and
the latest release can be easily installed using the command
install.packages("rrcov") library(rrcov)
To install the latest stable development version from GitHub, you can pull this repository and install it using
## install.packages("remotes") remotes::install_github("valentint/rrcov", build_opts = c("--no-build-vignettes"))
Of course, if you have already installed remotes
, you can skip the
first line (I have commented it out).
This is a basic example which shows you if the package is properly installed:
library(rrcov) data(hbk) (out <- CovMcd(hbk))
