Fastest way to repeatedly subset a data frame?
...s very, very slow. For a dataset of 62,000 rows and 253 list entries, it takes probably 5 minutes on a pentium D. An implementation of this kind of subsetting using hashtables in C# takes a neglible amount of time. I am open to any suggestions about data format, methods, anything.
