Sorting landmarks

[Maia R.]

I would like to sort a sequence of anatomical landmarks wrt to the landmark ID.

I tried this:

===

val refIDs = refLMs.map(lm => lm.id).sorted

But how to sort the point as well with the corresponding id ?

Could some one have an idea on how to do that ?

Thank you

Best regards

Hi Maia,

this should do the job (provided that lm.id is actually an integer):

val sorted = refLMs.map(lm => (lm.id.toInt, lm.point)).sortBy(_._1)

Dear Max, 

Thank you very much, it works (I just suppress .toInt as my ID are of String type).

I had also to add Landmark conversion, otherwise I got error, so final solution is (my landmarks are anatomical ones with String name):

val sorted = refLMs.map(lm => (lm.id, lm.point)).sortBy(_._1).map(f  => Landmark(f._1, f._2))

Thank you very much,

Best regards
