## Distance of potential nucleosome dyad

### Description

Calculate the distance of potential nucleosome dyad and the linear model for V.

### Usage

    distanceDyad(vPlotOut, fragLenRanges = c(60, 180, 250), draw = TRUE,
      ...)

### Arguments

`vPlotOut` | The output of vPlot.
`fragLenRanges` | A numeric vector (length=3) for fragment size of nucleosome free and mono-nucleosome. Default c(60, 180, 250).
`draw` | Plot the results or not. Default TRUE.
`...` | Prameters could be passed to plot.

### Value

an invisible list with distance of nucleosome and the linear model.
