Exactly how do you want to convert it? It looks like you have columns that are not integers, but factors. Can you provide an 'str' of the dataframe so that we can see what the structure is. Can you also provide an idea of what you want as output; you say a multiple list of integers, but I am not sure what you are expecting. If you have factors, some appear to be character data; how are those to be handled? A small subset of the data would be helpful.
