On: Is a Dataframe Just a Table? (2019) [pdf]

[idclip]

Oh interesting, because i wanted to say “everything is a tensor” before i write the long post

So generics and mixed types is where it hits a wall with tables? Though those mixed structured can just be broken down to collections of tables and enumerated, no? Then call the table of tables a table again?

Also why is a matrix not a table? Because its a super type ?

A matrix is not a table because all the columns need to be the same type. While you can convert a matrix to a table, the converse is not true.

(I assume this is what he meant, as it is the case in R.)
