%description
This R package can be used to generate artificial data conditionally on
pre-specified (simulated or user-defined) relationships between the
variables and/or observations. Each observation is drawn from a
multivariate Normal distribution where the mean vector and covariance
matrix reflect the desired relationships. Outputs can be used to evaluate
the performances of variable selection, graphical modelling, or clustering
approaches by comparing the true and estimated structures (B Bodinier et
al (2021) <arXiv:2106.02521>).
