DataFrame & Series
The tabular core of Deepbox, including DataFrame, Series, grouping, and shared dataframe types.
Tabular API
type AggregateFunction
export type AggregateFunction = "sum" | "mean" | "median" | "min" | "max" | "std" | "var" | "count" | "first" | "last";
Supported aggregation functions for DataFrame groupby operations.
type DataFrameData
export type DataFrameData = Record<string, unknown[]>;
Column-oriented data for DataFrame construction.
type DataFrameOptions
export type DataFrameOptions = { index?: (string | number)[]; columns?: string[]; copy?: boolean; };
Configuration options for DataFrame construction.
type DataValue
export type DataValue = number | string | boolean | null | undefined;
Data structure for DataFrame initialization.
type SeriesOptions
export type SeriesOptions = { name?: string; index?: (string | number)[]; copy?: boolean; };
Configuration options for Series construction.
DataFrame
Two-dimensional, size-mutable, potentially heterogeneous tabular data.
DataFrameGroupBy
GroupBy object for aggregation operations.
Series
One-dimensional labeled array capable of holding any data type.
