JSdist: Jensen-Shannon distance on columns

Description

JSdist takes a matrix of expression probabilites (calculated directly or output from makeprobs()) and returns a dist object of the pairwise Jensen-Shannon distances between columns

Usage

JSdist(mat,...)

Arguments

mat

A matrix of expression probabilities (e.g. from makeprobs())

...

Passthrough argument to as.dist()

Value

A dist object of pairwise J-S distances between columns.

Details

Returns pairwise Jensen-Shannon distance (in the form of a dist object) for a matrix of probabilities (by column)

References

None

Examples

mat<-matrix(sample(1:50,50),10)
probs<-makeprobs(mat)
js.distance<-JSdist(probs)
