Is there any api for categorical column statistic ?

DataSet.describe only calculate the statistics for numerical data, but not
for categorical column. R's summary method can also calculate statistical
for numerical data which is very useful for exploratory data analysis. Just
wondering is there any api for categorical column statistics as well or is
there any jira for it ? Thanks
