Headers for the 'xtensor' Library

The 'xtensor' C++ library for numerical analysis with multi-dimensional array expressions is provided as a header-only C++14 library. It offers an extensible expression system enabling lazy broadcasting; an API following the idioms of the C++ standard library; and tools to manipulate array expressions and build upon 'xtensor'.

Xtensor.R is an R package wrapping the xtensor-r bindings to the xtensor C++ multi-dimensional array library.

Packaging Xtensor.R

This section may be of interest to people working on packaging Xtensor.R for Linux distributions or other general-purpose packaging systems.

The Xtensor R package depends on the xtensor-r C++ header-only library.

• When installing the CRAN package the headers of xtensor-r and its dependencies are vendored in the R package.
• However, the conda-forge package does not vendor its dependencies.

The vendoring can be prevented by passing the --novendor option to the configure script, which can be passed to the R CMD INSTALL command in the following way:

R CMD INSTALL --build --configure-args='--novendor'
