tiledb (version 0.11.0)

tiledb_array-class: An S4 class for a TileDB Array

Description

This class aims to eventually replace tiledb_dense and tiledb_sparse provided equivalent functionality based on refactored implementation utilising newer TileDB features.

Slots

ctx

A TileDB context object

uri

A character despription with the array URI

is.sparse

A logical value whether the array is sparse or not

as.data.frame

A logical value

attrs

A character vector to select particular column ‘attributes’

extended

A logical value, defaults to TRUE, indicating whether index columns are returned as well.

selected_ranges

An optional list with matrices where each matrix i describes the (min,max) pair of ranges for dimension i

query_layout

An optional character value

datetimes_as_int64

A logical value

encryption_key

A character value

timestamp

A POSIXct datetime variable (deprecated, use timestamp_start)

as.matrix

A logical value

as.array

A logical value

query_condition

A Query Condition object

timestamp_start

A POSIXct datetime variable for the inclusive interval start

timestamp_end

A POSIXct datetime variable for the inclusive interval start

return_as

A character value with the desired tiledb_array conversion, permitted values are ‘asis’ (default, returning a list of columns), ‘array’, ‘matrix’,‘data.frame’, ‘data.table’ or ‘tibble’; the latter two require the respective packages installed

query_statistics

A logical value, defaults to ‘FALSE’; if ‘TRUE’ the query statistics are returned (as a JSON string) via the attribute ‘query_statistics’ of the return object.

sil

An optional and internal list object with schema information, used for parsing queries.

dumpbuffers

An optional character variable with a directory name (relative to /dev/shm) for writing out results buffers (for internal use / testing)

buffers

An optional list with full pathnames of shared memory buffers to read data from

ptr

External pointer to the underlying implementation
