In jasenfinch/metabolyseR: Methods for Pre-Treatment, Data Mining and Correlation Analyses of Metabolomics Data

Unsupervised random forest MDS plot

Description

A multidimensional scaling (MDS) plot of unsupervised random forest analysis

Usage

plotUnsupervisedRF(
  x,
  cls = "class",
  rf = list(),
  label = NULL,
  shape = FALSE,
  ellipses = TRUE,
  seed = 1234,
  title = "",
  legendPosition = "bottom",
  labelSize = 2,
  ...
)

## S4 method for signature 'AnalysisData'
plotUnsupervisedRF(
  x,
  cls = "class",
  rf = list(),
  label = NULL,
  shape = FALSE,
  ellipses = TRUE,
  seed = 1234,
  title = "",
  legendPosition = "bottom",
  labelSize = 2
)

## S4 method for signature 'Analysis'
plotUnsupervisedRF(
  x,
  cls = "class",
  rf = list(),
  label = NULL,
  shape = FALSE,
  ellipses = TRUE,
  seed = 1234,
  title = "",
  legendPosition = "bottom",
  labelSize = 2,
  type = c("pre-treated", "raw")
)

Arguments

x	object of class AnalysisData or Analysis
cls	sample information column to use for sample labelling
rf	list of additional parameters to pass to randomForest
label	info column to use for sample labels. Set to NULL for no labels.
shape	TRUE/FALSE use shape aesthetic for plot points. Defaults to TRUE when the number of classes is greater than 12
ellipses	TRUE/FALSE, plot multivariate normal distribution 95% confidence ellipses for each class
seed	random number seed
title	plot title
legendPosition	legend position to pass to legend.position argument of ggplot2::theme. Set to "none" to remove legend.
labelSize	label size. Ignored if label is NULL
...	arguments to pass to the appropriate method
type	raw or pre-treated data to plot

Examples

library(metaboData)

d <- analysisData(abr1$neg[,200:300],abr1$fact)

## Unsupervised random forest MDS plot
plotUnsupervisedRF(d,cls = 'day')
