In jaehyunjoo/poplin: LC/MS Metabolomics Data Processing Utilities

Description

Produce a box-and-whisker plot of the feature intensity values.

Usage

## Default S3 method:
poplin_boxplot(
  x,
  group,
  pre_log2 = FALSE,
  violin = FALSE,
  ylab = "Intensity",
  ...
)

## S3 method for class 'poplin'
poplin_boxplot(
  x,
  xin,
  group,
  pre_log2 = FALSE,
  violin = FALSE,
  ylab = "Intensity",
  ...
)

Arguments

x	A matrix or poplin object.
group	A discrete variable to visualize the grouping structure.
pre_log2	Logical controlling whether feature intensities are log2-transformed before visualization.
violin	Logical controlling whether a violin plot is drawn instead of the boxplot.
ylab	The title of y-axis of the plot.
...	Reserved for future use.
xin	Character specifying the name of data to retrieve from x when x is a poplin object

Value

A ggplot object.

Examples

data(faahko_poplin)

## sample group variable
group <- colData(faahko_poplin)$sample_group

## poplin object
poplin_boxplot(faahko_poplin, xin = "knn_cyclic", group = group)

## matrix
m <- poplin_data(faahko_poplin, "knn_cyclic")
poplin_boxplot(m, group = group)
