  .object,
  reduceProduction = 10,
  nClusters = 2,
  clusterOfInterest = 2,
  plotFilename = NULL,
  plotHeatmap = TRUE,
  plotBarPlot = TRUE,

)

Arguments

.object

RacipeSE object generated by sracipeSimulate function.

reduceProduction

(optional) Percentage to which production rate decreases on knockdown. Uses a default value of 10 percent.

nClusters

(optional) Number of clusters in the data. Uses a default value of 2.

clusterOfInterest

(optional) cluster number (integer) to be used for arranging the transcription factors

plotFilename

(optional) Name of the output file.

plotHeatmap

logical. Default TRUE. Whether to plot the heatmap or not.

plotBarPlot

logical. Default TRUE. Whether to plot the barplot.

clusterCut

integer or character. The cluster assignments.

plotToFile

logical. Default FALSE.

Value

List containing fraction of models in different clusters in the original simulations and after knowcking down different genes. Additionaly, it generates two pdf files in the results folder. First is barplot showing the percentage of different clusters in the original simulations and after knocking down each gene. The second pdf contains the heatmap of clusters after marking the models with cluster assignments.
