style as returned by Presto to an actual data.frameIt ‘defines’ a few extra “data types” to handle all types returned by Presto, like timestamps with time zones.
.json.tabular.to.data.frame(data, column.types, timezone)a list of lists
A character vector of (extended) data types
corresponding to each column. See .presto.to.R for a list
of possible values.
A data.frame of length(data) rows and
length(data[[1]]) columns.
If the items in data are named lists the column names will
be inferred from those names. Otherwise they will be
paste0('X', seq_along(data[[1]]))
Note that for NA values, data should have a NULL
item in the correct spot. Ragged arrays are not supported (i.e. all sublists
have to have the same length).
