Constructs a tiledb_array object backed by a persisted tiledb array uri

tiledb_array returns a new object. This class is experimental.

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,
  as.array = FALSE,
  query_condition = new("tiledb_query_condition"),
  timestamp_start = as.POSIXct(double(), origin = "1970-01-01"),
  timestamp_end = as.POSIXct(double(), origin = "1970-01-01"),
  return_as = get_return_as_preference(),
  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. Deprecated, use ‘timestamp_start’ instead
as.matrix	optional logical switch, defaults to "FALSE"; currently limited to dense matrices; in the case of multiple attributes in query a list of matrices is returned
as.array	optional logical switch, defaults to "FALSE"; in the case of multiple attributes in query a list of arrays is returned
query_condition	optional tiledb_query_condition object, by default uninitialized without a condition; this functionality requires TileDB 2.3.0 or later
timestamp_start	optional A POSIXct Datetime value determining the inclusive time point at which the array is to be openened. No fragments written earlier will be considered.
timestamp_end	optional A POSIXct Datetime value determining the inclusive time point until which the array is to be openened. No fragments written earlier later be considered.
return_as	optional 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. The existing as.* arguments take precedent over this.
ctx	optional tiledb_ctx
