DataSet transformation

[Lydia Ickler]

Hi all,

so I have a case class Spectrum(mz: Float, intensity: Float)

and a DataSet[Spectrum] to read my data in.

Now I want to know if there is a smart way to transform my DataSet into a two dimensional Array ?

Thanks in advance,

Lydia

Hi,

for that you have to collect the dataset to your local machine and then transform the collection into the array.

Note that this only advised for small data sets.
