Description

A function is used to draw the plot of the condition number of signature matrices of all sizes, from a handful of genes in one extreme to the whole signature in the other.

Usage

1
      condplot(step, cond)

Arguments

step

an array with the number of genes used to calculate the condition numbers of signature matrices, default stepwise = 20

cond

an array with the condition numbers of signature matrices

Value

a plot for the condition numbers of signature matrices

## toy data example:


      step <- seq(20,1000, by=20) #every 20 genes
      ## cell type-specific gene expression matrix:
      x.signature <- matrix(rexp(2000),ncol=2)
      sig.cond <- sapply(step, function(x) kappa(scale(x.signature[1:x,]))) 
      function (step, cond)
