Modules

• iter
  Producers, iterables and iterators.
• linalg
  Linear algebra.
• prelude
  ndarray prelude.

Macros

• R
  Execute R code by parsing and evaluating tokens.
• Rraw
  Execute R code by parsing and evaluating tokens but without expanding parameters.
• array
  Create an Array with one, two or three dimensions.
• azip
  Array zip macro: lock step function application across several arrays and producers.
• call
  Call a function or primitive defined by a text expression with arbitrary parameters. This currently works by parsing and evaluating the string in R, but will probably acquire some shortcuts for simple expessions, for example by caching symbols and constant values.
• concatenate
  Concatenate arrays along the given axis.
• data_frame
  Create a dataframe.
• extendr_module
  Define a module and export symbols to R Example:
• factor
  Create a factor.
• for_both
  Evaluate the provided expression for both Either::Left and Either::Right.
• global
  Get a global variable.
• lang
  A macro for constructing R langage objects.
• list
  Create a List R object from a list of name-value pairs.
• pairlist
  Create a Pairlist R object from a list of name-value pairs.
• r
  Convert a rust expression to an R object.
• reprint
  Print via the R error stream.

• s
  Slice argument constructor.
• stack
  Stack arrays along the new axis.
• stack_new_axisDeprecated
  Stack arrays along the new axis.
• sym
  The sym! macro install symbols. You should cache your symbols in variables as generating them is costly.
• test
  Macro for running tests.
• try_left
  Macro for unwrapping the left side of an Either, which fails early with the opposite side. Can only be used in functions that return Either because of the early return of Right that it provides.
• try_right
  Dual to try_left!, see its documentation for more information.
• var
  Get a local variable from the calling function or a global variable if no such variable exists.
