Factory method to create a Apache Arrow RDataFrame.

Parameters

[in]

table

an apache::arrow table to use as a source.

Creates a RDataFrame using an arrow::Table as input.

Parameters

[in]	table	the arrow Table to observe.
[in]	columnNames	the name of the columns to use In case columnNames is empty, we use all the columns found in the table
