Non-standard addition to NaN bit pattern to discriminate NA from NaN. 0x000007a2 == UInt32(1954) (I assume 1954 is the year of Ross's birth or something like that.)

Maps R type id (SXType) to its SXTypeInfo.

ASCII RData format IO stream wrapper.

Context for reading R bytecode.

Container that mimics R vector behaviour. Elements could be accessed either by indices as a normal vector, or (optionally) by string keys as a dictionary.

Native binary RData format IO stream wrapper.

TODO write readers

RDA (R data archive) reading context.

• Stores flags that define how R objects are read and converted into Julia objects.
• Maintains the list of R objects that could be referenced later in the RDA stream.

Abstract RDA format IO stream wrapper.

R vector object with explicit NA values.

Base class for all R types (objects) that can have attributes.

Representation of R's paired list-like structures (LISTSXP, LANGSXP). Unlike R which represents these as singly-linked list, RPairList uses vector representation.

Base class for RData internal representation of all R types. SEXPREC stands for S (R predecessor) expression record.

R symbol. Not quite the same as a Julia symbol.

Base class for all R vector-like objects.

R vector object.

Definition of R type.

XDR (machine-independent binary) RData format IO stream wrapper.

Creates RDAIO wrapper for io stream depending on its format specified by formatcode.

Register R object, so that it could be referenced later (by its index in the reference table).
