peak_time_difference: peak_time_difference

In Autotuner: Automated parameter selection for untargeted metabolomics data processing

Description

This function is designed to return a data.frame containing info on how

Usage

peak_time_difference(Autotuner)

Arguments

Autotuner

An Autotuner object containiing a table of peak width values extracted with the function peak_width_table.

Details

This function is designed to determine what are the retention time differences between peaks that are effectively the same between samples. The similarity in peaks is determined by a threshold in retention time similarity between peaks. This function returns the max peak width between samples, and the time difference between peaks across samples in a data frame object. The current and next row indexes are given to go back to the peaktable object to plot peaks.

Value

This function returns a data.frame of peaks matched over time.
