This is programming style, best practices type of question.

When converting a list to a data frame (eg to use in ggplot), what is "best"
way to store descriptive elements?

For example, a survfit object mostly maps to a data frame, but I would also
like to carry along the type, call, etc.

I'm inclined to make these attributes of the data frame.

Any better technique?
