Module robj 

R object handling.

See. Writing R Extensions

Fundamental principals:

• Any function that can break the protection mechanism is unsafe.
• Users should be able to do almost everything without using libR_sys.
• The interface should be friendly to R users without Rust experience.

Structs

Robj

Wrapper for an R S-expression pointer (SEXP).

Traits

AsTypedSlice

Generic access to typed slices in an Robj.

Attributes

Provides access to the attributes of an R object.

Eval

GetSexp

IntoRobj

This is an extension trait to provide a convenience method into_robj().

Length

RobjItertools

Extensions to iterators for R objects including RobjItertools::collect_rarray().

Slices

ToVectorValue

ToVectorValue is a trait that allows many different types to be converted to vectors. It is used as a type parameter to collect::<Robj>().

Types

Functions

fixed_size_collect

str_to_character

Returns an CHARSXP based on the provided &str.
