uplot_ri_vs_sample: Average Relative Intensity per Sample

In ume: Ultrahigh-Resolution Mass Spectrometry Data Evaluation for Complex Organic Matter

Average Relative Intensity per Sample

Description

Creates a bar plot showing the median relative intensity (default: norm_int) for each sample (grouped by file_id). The overall dataset-wide median and standard deviation are shown in the title.

Usage

uplot_ri_vs_sample(
  df,
  int_col = "norm_int",
  grp = "file_id",
  col = "grey",
  logo = TRUE,
  width = 0.3,
  gg_size = 12
)

Arguments

df	A data.table containing at least: a column with relative intensity values (int_col) a sample or file identifier (grp)
int_col	Character. Column name containing relative intensity values.
grp	Character. Column name specifying sample / file grouping.
col	Character. Fill color for bars.
logo	Logical. If TRUE, adds a UME caption.
width	Numeric. Width of bars (default 0.3).
gg_size	Base text size for theme_uplots(). Default = 12.
