Description

Inheritance function from nbh that receives an object of GRanges class with additional column of read counts (for each strand) and call nbh.integer to derive the most probable sequence of hidden states

Usage

1
2
## S3 method for class 'GRanges'
nbh(x, K, ...)

Arguments

x

GRanges with 'values' slot used for bin counts in 1D vector of integers.

K

Number of hidden states.

...

Extra arguments passed to nbh.integer for the actual HMM computation.

Value

binGR

GRanges of bin counts with metadata slot saved for the optimized HMM parameters including alpha, beta for the K negative binomial mixture components and TRANS (the transition probabilities)
