[EXAMPLE] - fromDataFrame()

[cgiachalis]

fromDataFrame() example doesn't succeed for two reasons. See inline comments below.

uri <- tempfile()
## turn factor into character
irisdf <- within(iris, Species <- as.character(Species))
fromDataFrame(irisdf, uri)
arr <- tiledb_array(uri, return_as="data.frame", sparse=FALSE) # NOTE: `sparse` argument not in `tiledb_array`
newdf <- arr[]
all.equal(iris, newdf) # NOTE:  iris -> irisdf

Nice catch, thank you. That does indeed need a hand. A simpler, updated one is

uri <- tempfile()
fromDataFrame(iris, uri)
arr <- tiledb_array(uri, return_as="data.frame", extended=FALSE)
newdf <- arr[]
all.equal(iris, newdf, check.attributes=FALSE)  # extra attribute on query in newdf
all.equal(as.matrix(iris), as.matrix(newdf))	# also strips attribute

I can probably also remove the \dontrun{} which I don't think is currently needed.
