Overview

About

Maintained by Andrew IskauskasCRAN page ↗GitHub ↗Website ↗Issues ↗

A set of objects and functions for Bayes Linear emulation and history matching. Core functionality includes automated training of emulators to data, diagnostic functions to ensure suitability, and a variety of proposal methods for generating 'waves' of points. For details on the mathematical background, there are many papers available on the topic (see references attached to function help files or the below references); for details of the functions in this package, consult the manual or help files.

Changes in 1.6.2

Bug fixes

Fixed edge-case in diagnostics where emulators could be reordered incorrectly
Fixed problem where covariance terms were set to zero in variance emulator construction
Removal of ggbeeswarm dependency ahead of package archival.

Minor changes

Modifications to line and lhs sampling in generate_new_design for stability
diagnostic_pass now respects beta.var = TRUE if it retrains emulators
hit_by_wave can now plot number of hits by relative to individual targets of a collection
General optimisation, particularly leveraging certain prior specifications for emulators (for example, if no prior correlation between beta and u exists)
Proto_emulator now accepts full covariance matrix returns and handles them appropriately.

Major changes

import_emulator_from_json and export_emulator_to_json added, to allow lightweight export/import for use with other systems

Show all changes in 1.6.2Hide the rest of the changes in 1.6.2

Principal outputs for emulation can be determined using prin_vars, for high-dimensional output spaces
Maximin sampling used in point generation has been given its own function, maximin_sample. generate_new_design can accordingly be told to skip the point thinning via thin = FALSE.

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("hmer", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("andy-iskauskas/hmer")

Development version from andy-iskauskas/hmer. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-hmer

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-hmer

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-hmer

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
