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 = "ROW_MAJOR", tile_order = "ROW_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 of size two specifying the integer domain of the row
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.
