How to make a dataframe with lists or vectors as its elements
$begingroup$
This is something I have been wondering for ages but I am never able to get an answer.
I am trying to understand how to make a dataframe in R, where each element of the dataframe is itself a vector or a matrix.
For example, lets say we have a regular vector V with elements being real numbers.
Then to acess any number we would have
V[3] which would give the third element of said vector.
Now I want to know how to do this with say a dataframe D,
where each element of the dataframe is itself a vector or matrix, so that say
D[3] is not a real number, but a vector.
How can this be done in R?
Thanks all

Dataframe is a representation of 2 D matrix in R. R does not support MultiIndex dataframes that can represent more complex structures.
Maybe you can model the problem as a Tensor ( https://cran.r-project.org/web/packages/tensorr/vignettes/introduction.html , https://www.rdocumentation.org/packages/rTensor/versions/1.4/topics/Tensor-class)
