pandas.DataFrame supported APIs

The following table lists both implemented and not implemented methods. If you have need of an operation that is listed as not implemented, feel free to open an issue on the http://github.com/elastic/eland, or give a thumbs up to already created issues. Contributions are also welcome!

The following table is structured as follows: The first column contains the method name. The second column is a flag for whether or not there is an implementation in Modin for the method in the left column. Y stands for yes, N stands for no.

https://github.com/adgirish/kaggleScape/blob/master/results/annotResults.csv represents a prioritised list.
