In OlinkAnalyze: Facilitate Analysis of Proteomic Data from Olink

Function to plot the NPX distribution by panel

Description

Generates boxplots of NPX vs. SampleID colored by QC_Warning (default) or any other grouping variable and faceted by Panel using ggplot and ggplot2::geom_boxplot.

Usage

olink_dist_plot(df, check_log = NULL, color_g = "QC_Warning", ...)

Arguments

df	NPX data frame in long format. Must have columns SampleID, NPX and Panel
check_log	A named list returned by check_npx(). If NULL, check_npx() will be run internally using df.
color_g	Character value indicating which column to use as fill color. (default: QC_Warning).
...	Color option passed to specify color order.

Value

An object of class "ggplot" which displays NPX distribution for each sample per panel

Examples

# Optional: check and clean dataset
check_log <- OlinkAnalyze::check_npx(
  df = npx_data1
)

cleaned_data <- OlinkAnalyze::clean_npx(
  df = npx_data1,
  check_log = check_log
)

OlinkAnalyze::olink_dist_plot(
  df = npx_data1,
  check_log = check_log,
  color_g = "QC_Warning"
)

OlinkAnalyze::olink_dist_plot(
  df = cleaned_data,
  check_log = check_log,
  color_g = "QC_Warning"
)
