loadCallcenterData {Rfssa}

Load Callcenter Data from GitHub Repository

Description

This function retrieves the Callcenter dataset from the Rfssa_dataset repository on GitHub (https://github.com/haghbinh/dataset/Rfssa_dataset). The Callcenter dataset represents a small call center for an anonymous bank. It provides precise call timing data from January 1 to December 31, 1999. The data is aggregated into 6-minute intervals on each day. The returned object is a raw dataset in dataframe format; it is not a 'funts' class object. This raw data can then be further processed and converted into a 'funts' object named 'Callcenter'. See funts for more details on working with functional time series of class 'funts'.

Usage

loadCallcenterData()

Format

a dataframe with 87,600 rows and 5 variables:

calls

number of calls in a 6-minute aggregated interval.

u

numeric vector indicating the aggregated interval.

Date

date and time of call count recording.

Day

weekday associated with Date.

Month

month associated with Date.
