Subject: Make sure a data frame has been "fun through" a function
Hello,
I would like to add something to a data frame that is 1) invisible to the
user, 2) has no side effects, and 3) I can test for in a following
function. Is this possible? I am exploring classes and attributes and I
have thought about using a list (but 1 and 2 not satisfied). Any help would
be greatly appreciated.
I did not provide a reproducible example because I see this as more of a R
language question, but I will be happy to make a toy example if that would
help.
I appreciate all of the help.
kindest regards,
