[R] Fwd: help

Hi:

It's not at all clear to me what you want to do. Is each component of
your list a data frame with the same structure? Are you trying to
combine them into one data frame? If so, then try

mydata <- do.call(rbind, c)

where c is the name of the list. (Not a good choice of name, by the
way - c() is a very common function in R and it's not wise to assign
another object to that name.)

If you want to do something else, perhaps you could clarify your
intentions for the list.

HTH,
Dennis
