Create a TileDB Dense Array from a given <code>data.frame</code> Object — fromDataFrame • tiledb

The supplied data.frame object is (currently) limited to integer, numeric, or character columns.

fromDataFrame(obj, uri)

Arguments

obj	A `data.frame` object.
uri	A character variable with an Array URI.

Value

Null, invisibly.

Details

The create (Dense) Array will have as many attributes as there are columns in the data.frame. Each attribute will be a single column.

At present, factor variable are converted to character.

Examples

ctx <- tiledb_ctx(limitTileDBCores())
if (FALSE) {
uri <- tempfile()
## turn factor into character
irisdf <- within(iris, Species <- as.character(Species))
fromDataFrame(irisdf, uri)
arr <- tiledb_dense(uri, as.data.frame=TRUE)
newdf <- arr[]
all.equal(iris, newdf)
}
