In-memory Daf store.

Source: R/memory_daf.R
memory_daf.Rd

A concrete DafWriter backed entirely by R environments — no disk, no mmap. Scalars, axes, vectors, and matrices live in nested environments (hash tables) under the internal property:

Usage

memory_daf(name = "memory")

Arguments

name

Human-readable identifier. Defaults to "memory".

Value

A MemoryDaf instance.

Details

  • internal$scalars : env(name -> value)

  • internal$axes : env(axis -> list(entries = character, dict = env))

  • internal$vectors : env(axis -> env(name -> vector))

  • internal$matrices : env(rows_axis -> env(columns_axis -> env(name -> matrix)))

Examples

d <- memory_daf(name = "scratch")
add_axis(d, "cell", c("A", "B", "C"))
set_vector(d, "cell", "donor", c("d1", "d2", "d1"))
