tiledb (version 0.9.2)

tiledb_array: Constructs a tiledb_array object backed by a persisted tiledb array uri

Description

tiledb_array returns a new object. This class is experimental.

Usage

tiledb_array(
  uri,
  query_type = c("READ", "WRITE"),
  is.sparse = NA,
  as.data.frame = FALSE,
  attrs = character(),
  extended = TRUE,
  selected_ranges = list(),
  query_layout = character(),
  datetimes_as_int64 = FALSE,
  encryption_key = character(),
  timestamp = as.POSIXct(double(), origin = "1970-01-01"),
  as.matrix = FALSE,
  ctx = tiledb_get_context()
)

Arguments

uri

uri path to the tiledb dense array

query_type

optionally loads the array in "READ" or "WRITE" only modes.

is.sparse

optional logical switch, defaults to "NA" letting array determine it

as.data.frame

optional logical switch, defaults to "FALSE"

attrs

optional character vector to select attributes, default is empty implying all are selected

extended

optional logical switch selecting wide ‘data.frame’ format, defaults to "TRUE"

selected_ranges

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

query_layout

optional A value for the TileDB query layout, defaults to an empty character variable indicating no special layout is set

datetimes_as_int64

optional A logical value selecting date and datetime value representation as ‘raw’ integer64 and not as Date, POSIXct or nanotime objects.

encryption_key

optional A character value with an AES-256 encryption key in case the array was written with encryption.

timestamp

optional A POSIXct Datetime value determining where in time the array is to be openened.

as.matrix

optional logical switch, defaults to "FALSE"; currently limited to dense matrices; in the case of multiple attributes in query lists of matrices are returned

ctx

tiledb_ctx (optional)

Value

tiledb_array object
