Merge split peaks

Combines split peaks into a single column of the peak table.

Usage

merge_peaks(peak_table, peaks, method = c("max", "sum"))

Arguments

peak_table

A peak_table object from get_peaktable.

peaks

A vector specifying the names or indices of peaks to be merged.

method

Method to merge peaks. Either "max" to select the largest peak from each sample or "sum" to add the peaks together.

Value

A peak table similar to the input peak table, but where the specified columns are combined.

Details

In each sample, method = "max" keeps the largest of the specified peaks and method = "sum" adds them. The result replaces the peak with the highest mean across samples, whose metadata is retained; the other peaks are removed.
