How to insert a dataset inside another one?

Ehud Behar

Posted 7 months ago

I have the following two datasets: Dataset[{ <\|"Date" -> DateObject[{2024, 1, 10}]\|>, <\|"Collection-area" -> Quantity[3, ("Centimeters")^2]\|>, <\|"Integration Time" -> Quantity[2.1, "Seconds"]\|> }] and Dataset[{ <\|"\[Lambda]" -> Quantity[195.050, "Nanometers"], "r" -> Quantity[2.9, "Watts"]\|>, <\|"\[Lambda]" -> Quantity[196.000, "Nanometers"], "r" -> Quantity[2.1, "Watts"]\|>, <\|"\[Lambda]" -> Quantity[196.050, "Nanometers"], "r" -> Quantity[2.6, "Watts"]\|> }] How can I merge them into a new dataset that looks the following:

and

Dataset[{

  <|"\[Lambda]" -> Quantity[196.000, "Nanometers"], "r" -> Quantity[2.1, "Watts"]|>,
  <|"\[Lambda]" -> Quantity[196.050, "Nanometers"], "r" -> Quantity[2.6, "Watts"]|>
  }]

To approximate the look you want, is this good enough? Column[{d1, d2}, Alignment -> Center, Spacings -> 1, Frame -> True, FrameStyle -> Gray] Out[] = Otherwise, you can alternatively do this: Dataset[{ <\|"Date" -> DateObject[{2024, 1, 10}]\|>, <\|"Collection-area" -> Quantity[3, ("Centimeters")^2]\|>, <\|"Integration Time" -> Quantity[2.1, "Seconds"]\|>, <\|"\[Lambda],r" -> d2 }]

For your expected dataset, did you use actual code to create that, or is it just a graphic or some other "fake". If I could see the actual structure of that dataset, it would be easier. But anyway, in the meantime, this is close: d1 = Dataset[{<\|"Date" -> DateObject[{2024, 1, 10}]\|>, <\|"Collection-area" -> Quantity[3, ("Centimeters")^2]\|>, <\|"Integration Time" -> Quantity[2.1, "Seconds"]\|>}]; d2 = Dataset[{<\|"\[Lambda]" -> Quantity[195.050, "Nanometers"], "r" -> Quantity[2.9, "Watts"]\|>, <\|"\[Lambda]" -> Quantity[196.000, "Nanometers"], "r" -> Quantity[2.1, "Watts"]\|>, <\|"\[Lambda]" -> Quantity[196.050, "Nanometers"], "r" -> Quantity[2.6, "Watts"]\|>}]; Dataset[Append[d1, Merge[d2, Dataset]]]
