Create a TileDB Array

Source: R/tdb_array.R
tdb_array_create.Rd

Given a TileDB schema, it will create an array and instantiate a TileDBArrayExp object. The array will be opened at the given mode and kept opened. It can be accessed via active field $object.

Usage

tdb_array_create(uri, sch, mode = "WRITE", ctx = NULL)

Arguments

uri

URI path for the TileDB object.

sch

A TileDB schema. See constructor tiledb::tiledb_array_schema().

mode

Mode to open: either "READ" or "WRITE" (default).

ctx

A TileDB Context. See tiledb::tiledb_ctx().

Value

A TileDBArrayExp, R6 object.

Examples

if (FALSE) { # interactive()
suppressMessages(library(tiledb))

# construct schema
schema <- tiledb_array_schema(
 dom = tiledb_domain(dims = tiledb_dim("id", c(1L, 4L), 4L, "INT32")),
 attrs = tiledb_attr("model", type = "ASCII"))

# uri path
uri <- tempfile()

# create and open array at WRITE mode
arrobj <- tdb_array_create(uri, sch = schema, mode = "WRITE")

arrobj$schema_info()

arrobj$mode # WRITE
}
