data.frame object is (currently) limited to integer,
numeric, or character. In addition, three datetime columns are supported
with the R representations of
fromDataFrame( obj, uri, col_index = NULL, sparse = FALSE, allows_dups = sparse, cell_order = "COL_MAJOR", tile_order = "COL_MAJOR", filter = "ZSTD", capacity = 10000L, tile_domain = NULL, tile_extent = NULL, debug = FALSE )
A character variable with an Array URI.
An optional column index, either numeric with a column index, or character with a column name, designating an index column; default is NULL implying an index column is added when the array is created
A logical switch to select sparse or dense (the default)
A logical switch to select if duplicate values are allowed or not, default is the same value as ‘sparse’.
A character variable with one of the TileDB cell order values, default is “COL_MAJOR”.
A character variable with one of the TileDB tile order values, default is “COL_MAJOR”.
A character variable vector, defaults to ‘ZSTD’, for one or more filters to be applied to each attribute;
A integer value with the schema capacity, default is 10000.
An integer vector or list or
An integer value for the tile extent of the row dimensions;
Logical flag to select additional output
The created (dense or sparse) array will have as many attributes as there
are columns in the
data.frame. Each attribute will be a single column.
For a sparse array, one or more columns have to be designated as dimensions.
At present, factor variable are converted to character.
