ColNoiseBC function

Barplots of Column Noise for Biclusters

Draws barplots of column noise of chosen biclusters. This plot can be helpful in determining which column label is often zero in noisy biclusters.

ColNoiseBC(result, matrix, BC = 1:result@Number, plot.type = "device",
  filename = "ColNoise")

Arguments

• result: A Biclust Object.

• matrix: Accompanying binary data matrix which was used to obtain result.

• BC: Numeric vector to select of which BC's a column noise bar plot should be drawn.

• plot.type: Output Type

  • "device": All plots are outputted to new R graphics devices (default).
  • "file": All plots are saved in external files. Plots are joint together in a single .pdf file.
  • "other": All plots are outputted to the current graphics device, but will overwrite each other. Use this if you want to include one or more plots in a sweave/knitr file or if you want to export a single plot by your own chosen format.

• filename: Base filename (with/without directory) for the plots if plot.type="file" (default="RowCoverage").

Examples

## Not run:

data <- matrix(sample(c(0,1),100*100,replace=TRUE,prob=c(0.9,0.1)),nrow=100,ncol=100)
data[1:10,1:10] <- 1 # BC1
data[11:20,11:20] <- 1 # BC2
data[21:30,21:30] <- 1 # BC3
data <- data[sample(1:nrow(data),nrow(data)),sample(1:ncol(data),ncol(data))]
result <- bibit2(data,minr=5,minc=5,noise=1)
ColNoiseBC(result=result,matrix=data,BC=1:3)
## End(Not run)
