plotLong: Plot Longitudinal Profiles by Cluster

In timeOmics: Time-Course Multi-Omics data integration

Description

This function provides a expression profile representation over time and by cluster.

Usage

plotLong(
  object,
  time = NULL,
  plot = TRUE,
  center = TRUE,
  scale = TRUE,
  title = "Time-course Expression",
  X.label = NULL,
  Y.label = NULL,
  legend = FALSE,
  legend.title = NULL,
  legend.block.name = NULL
)

Arguments

object	a mixOmics result of class (s)pca, (s)pls, block.(s)pls.
time	(optional) a numeric vector, the same size as ncol(X), to change the time scale.
plot	a logical, if TRUE then a plot is produced. Otherwise, the data.frame on which the plot is based on is returned.
center	a logical value indicating whether the variables should be shifted to be zero centered.
scale	a logical value indicating whether the variables should be scaled to have unit variance before the analysis takes place.
title	character indicating the title plot.
X.label	x axis titles.
Y.label	y axis titles.
legend	a logical, to display or not the legend.
legend.title	if legend is provided, title of the legend.
legend.block.name	a character vector corresponding to the size of the number of blocks in the mixOmics object.

Value

a data.frame (gathered form) containing the following columns:

time	x axis values
molecule	names of features
value	y axis values
cluster	assigned clusters
block	name of 'blocks'
