search for: r0000710a

...an subset a list based on some criterion as subset() is designed for vectors, matrices or dataframes. For example, I can use the following: tt <- apply(data, 2, table) Which returns an object of class list. Here is some sample output from tt $R0235940b 0 1 9 2004 1076 15361 $R0000710a 0 9 2 18439 $R0000710b 0 1 9 3333 3941 11167 tt$R0000710a meets my criteria and I would want to be able to easily find this instead of rolling through the entire output. Is there a way to subset this list to identify the columns which meet the criteria I note above...
