Tabular data processing for Continuous REPresentation

pip install git+https://github.com/eurobios-mews-labs/crep

This simple module aims at providing some function to tackle tabular data that have a continuous axis. In situations, this index can represent time, but this tool was originally developed to tackle rail way description.

This simple tools helps providing tools to represent a linear structure (cable, rail, beam, pipe) whose characteristics are piece-wize constant (of strongly heterogeneous length)

Basic usage

• Merge function merge together two dataframe

import pandas as pd

from crep import merge


df_left = pd.DataFrame(
    dict(id=[2, 2, 2],
         t1=[0, 100, 120],
         t2=[100, 120, 130],
         data1=[0.2, 0.1, 0.5])
)
df_right = pd.DataFrame(
    dict(id=[2, 2, 2],
         t1=[0, 80, 100],
         t2=[70, 100, 140],
         data2=[0.1, 0.3, 0.2])
)

ret = merge(data_left=df_left,
            data_right=df_right,
            id_continuous=["t1", "t2"],
            id_discrete=["id"],
            how="outer")

Yield the following result
