Apply Peak Refinement

Description

Function to apply peak picking parameters on a data subset.

Usage

apply_peak_refinement(
  data,
  expand_rt = 2,
  expand_mz = 0,
  ppm = 10,
  min_prop = 0.75
)

Arguments

data	An MSnExp object in centroid mode.
expand_rt	Numeric. Specifies the range to expand retention time during peak merging. Default is 2.
expand_mz	Numeric. Specifies the range to expand m/z during peak merging. Default is 0.
ppm	Numeric. Parts per million tolerance for peak merging.
min_prop	Numeric. Minimum proportion of overlapping intensity required to merge peaks. Default is 0.75.

Details
