calcWeights: Calculate bin weights using B-Spline

In larsgr/BSplineMI: Mutual information using B-Spline smoothed bins

Description

Takes an expression matrix and calculates for each value the weights for each bin using B-Splines of a given order.

Usage

calcWeights(x, nBins, splineOrder)

Arguments

x	Gene expression matrix with genes in rows and samples in columns
nBins	Number of bins
splineOrder	Spline order

Value

3-dimensional array of weights with dimensions: nBins x samples x genes

Examples

x <- matrix(0:100,nrow=1)
w <- calcWeights(x,nBins = 5,splineOrder = 3)
plot(NULL,xlim=c(0,100),ylim=c(0,1),xlab="x",ylab="weight")
for(i in 1:dim(w)[1]){
  lines(x[1, ],w[i, ,1],col=rainbow(dim(w)[1])[i])
}
