quickFuzz: quickFuzz

In TimiRGeN: Time sensitive microRNA-mRNA integration, analysis and network generation tool

Description

Plots fuzzy clusters. Each different cluster created will represent a different temporal behaviour. Depending on the data, more or fewer cluster may be appropriate. Use clusterCheck to influence this decision before moving onto quickFuzz. Each line in a cluster represents a pathway. Pathways are divided by colour. The more intense the colour of a line, the stronger they fit a particular cluster / temporal behaviour. Fuzzy clustering is a soft clustering approach where objects are not divided into fixed clusters. Each pathway can exist in each cluster but each pathway will differ on the degree to which they fit to each cluster. Look into the clusterData dataframe created by createClusters to see this. If a cluster peaks interest, continue to analysis of that cluster with the returnCluster function.

Usage

quickFuzz(Mfuzzdata, Clusters, W, background, labelcol, axiscol,
axisline, subcol, ylab)

Arguments

Mfuzzdata	A large ExpressionSet object which contain fuzzy clustering data. This is output from the createClusters function. The Expressionset object should be stored as an experiment in the MAE used in the createClusters function.
Clusters	A large list containing information about clusters, statistics and phenodata. This is output from the createClusters function. The list should be stored as metadata in the MAE used in the createClusters function.
W	TRUE or FALSE? Should the plot be shown in a new window? Default is TRUE.
background	Plot background colour. Default is black.
labelcol	Plot labels colour. Default is yellow.
axiscol	Plot axis labels colour. Default is white.
axisline	Plot axis line colour. Default is white.
subcol	Plot sub title colour. Default is yellow.
ylab	y axis label. Default is "Genes found in data and pathway".

Value

A plot of different clusters showing how the number of genes found to be significant varies between the input data and wikipathways. These variations are captured as temporal behaviours and are clustered.

Examples

MAE <- MultiAssayExperiment()

metadata(MAE)[["e_list"]] <- e_list_mouse

metadata(MAE)[["w_list"]] <- w_list_mouse[1:10]

MAE <- wikiMatrix(MAE, ID_list = metadata(MAE)[[1]],
                  wp_list = metadata(MAE)[[2]])

MAE <- turnPercent(MAE = MAE,
                   wikiMatrix = assay(MAE, 1))

MAE <- createClusters(MAE, method = "c",
                      percentMatrix = assay(MAE, 2),
                      noClusters = 2, variance = 0.99)

quickFuzz(Mfuzzdata = experiments(MAE)[[4]],
          Clusters = metadata(MAE)[[3]], W = FALSE)
