My student and I both loaded the same dataset, installed the same packages, and were running the same code. When I run "frq" I get a frequency table and the variable is labeled as "n...

Suppose I'd like to traverse case class generic representation as described here I've defined some typeclass to describe fields: trait Described[X] extends (X => String) object Described{ de...

I'm thinking of doing something similar to Safely copying fields between case classes of different types but with reordered fields, i.e. case class A(foo: Int, bar: Int) case class B(bar: Int, foo...

I'm trying to parametrize a method that needs to work on a generic type A for which a LabelledGeneric can be retrieved. Here's the naive approach case class Foo(bar: String, baz: Boolean) def par...

Consider the following example: import shapeless._ case class Foo(bar: String, baz: Boolean) val labl = LabelledGeneric[Foo] Now, the type of labl is (prettified) LabelledGeneric[Foo] { type ...
