In dr-consulting/ibi_VizEdit: Open-Source Software for Processing and Editing Heart Rate Data

Description

time_center takes a PPG and/or IBI file and centers it at the very start of a task file. The effect is to cut off any data prior to the initial time stamp and to set that value to 0, representing the start of the condition or conditions of interest.

Usage

time_center(x, time_col = "Time", timing_series = NULL)

Arguments

x	PPG or IBI data.frame
time_col	the name of the column in x that contains the time data
timing_series	the name of the vector that contains timestamps for the initial task and subsequent tasks. Must be formatted such that the element is the start of the first task/condition, the second element is the end of that task, the third is start of the second condition/task, the fourth is the end of that task and so on.

Value

a re-coded version of the inputs with new timing
