Plot the retention time vs delta precursor mass

plot_rt_vs_delta.Rd

It's useful to assess the relationship between retention time and delta precursor mass as a quality control step. There should be little or no relationship

Usage

plot_rt_vs_delta(
  obj,
  rt_col = "RT.in.min.by.Search.Engine.Sequest.HT",
  delta_ppm_col = "Delta.M.in.ppm.by.Search.Engine.Sequest.HT"
)

Arguments

obj

SummarisedExperiment containing peptide-level output from Proteome Discoverer.

rt_col

string. Name of column with retention time

delta_ppm_col

string. Name of column with the Delta precursor mass

Value

Returns a ggplot with the RT vs delta PPM
