ABCbarplot {DataVisualizations}

Barplot with Sorted Data Colored by ABCanalysis

Description

This plot can be read like a scree plot for PCA. It allowed to select the most important values visually.

Usage

ABCbarplot(Data,

Colors=DataVisualizations::DefaultColorSequence[1:3],

main,xlab,ylab="Value")

Arguments

Data

[1:n] vector of Data, e.g. eigenvalues of PCA

Colors

three colors for A, B and C

main

title of plot

xlab

xlabel

ylab

ylabel

Details

ABC analysis is explained in ABCanalysis. The visualization is based on ggplot2.

Value

List V of

ABCanalysis

output of ABCanalysis

ggobject

object of ggplot2 plotted

DF

Data frame if another plot should be done manually
