## Interval plot GRanges

### Description

Interval plot GRanges

### Usage

    plot_intervals(
      gr,
      xref = "targetname",
      y = default_y(gr),
      nperchrom = 2,
      nchrom = 4,
      color_var = "targetname",
      facet_var = "seqnames",
      linetype_var = default_linetype(gr),
      size_var = default_size_var(gr),
      alpha_var = default_alpha_var(gr),
      title = NULL,
      scales = "free"
    )

### Arguments

`gr` | `GRanges-class`
`xref` | gr var used for scaling x axis
`y` | 'names' (default) or name of gr variable
`nperchrom` | number (default 1): n head (and n tail) targets shown per chromosome
`nchrom` | number (default 6) of chromosomes shown
`color_var` | 'seqnames' (default) or other gr variable
`facet_var` | NULL(default) or gr variable mapped to facet
`linetype_var` | NULL (default) or gr variable mapped to linetype
`size_var` | NULL (default) or gr variable mapped to size
`alpha_var` | NULL or gr variable mapped to alpha
`title` | NULL or string: plot title
`scales` | 'free', 'fixed', etc

### Value
