Hi
I would like to have a data.frame, where one column contains functions,
and another one lists. i.e.:
FUN - function(l) {return(l$a+l$b+l$c}
LIST - list(a=1, b=2, c=3)
d - data.frame(fun=FUN, no=LIST, value=2, b=TRUE)
FUN - function(l)
It sounds like you want to use a list instead of a dataframe,
especially if the elements are a different length.
d - list() # initialize
d[[length(d) + 1]] - list() # extend
d[[length(d)]]$fun - sin # add a function
d[[length(d) + 1]] - list() # extend again
d[[length(d)]]$fun - cos #

No - I would like to have a data,frame. I am aware of the differences,
but as far as I understand, each column in a data.frame can have a
3 matches
