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

It's a hack but worked in my case.

lapply(my_list, FUN=function(x){data.frame(as.matrix(x),stringsAsFactors = F)})
