Create a dust odin model

Description

Compile an odin model to work with dust.

Usage

odin_dust(x, ..., options = NULL)

odin_dust_(x, ..., options = NULL)

Arguments

x

Either the name of a file to read, a text string (if length is greater than 1 elements will be joined with newlines) or an expression.

...

Arguments passed to odin_dust_options, including real_type, gpu, verbose, workdir, no_check_unused_equations and rewrite_dims.

options

An odin::odin_options or odin_dust_options object. If given it overrides arguments; if it is already a odin_dust_options object it is returned unmodified. Otherwise it is passed through to odin::odin_options where it will override arguments in ... but respond to the odin_dust specific options (real_type, etc)

Details

Note that this does not (yet) support the full odin output object, instead creating the more limited dust interface. However, for many uses this should be considerably faster than the interface that odin normally uses (built on dde).

Including custom code

When including custom C++ code you may want to set additional options in order to enable compilation. You can do this by including pseudo-attributes

  • ⁠// [[odin.dust::cpp_std(C++17)]]⁠ - use this to change the C++ standard used in compilation; this is passed to dust::dust() as the cpp_std option. It is only necessary to pass in values greater than C++11 at present as that is dust's default.

  • ⁠// [[odin.dust::linking_to(pkg)]]⁠ - use this to make include files present in an R package (e.g., BH) available. You can use as many of these attributes as you need.
