Removing attributes of columns in data.frames on multilevel lists in R

Question

How do I remove the attributes of the following columns of data.frames on a nested list in R on the fly?

List of 1
 $ 0021400001:List of 19
   $ GameSumma         


        

Answer 1

You could write a function that works on one entry in the list, e.g.

one_entry <- function(x) {
    for (i in length(x)) attr(x[[i]], "names") <- NULL
    return(x)
}

and then run lapply:

lapply(my_list, FUN=one_entry)

where mylist is the data structure in the question.
