QuantitativeTrack-class {igvR} | R Documentation

## Constructor for QuantitativeTrack

### Description

`QuantitativeTrack` creates an `IGV` track for genomic tracks in which a numerical value is associated with each reported location.

### Usage

    QuantitativeTrack(trackName, quantitativeData, fileFormat = c("wig",
      "bigWig", "bedGraph"), color = "gray", sourceType = "file",
      autoscale = TRUE, min = NA_real_, max = NA_real_,
      visibilityWindow = 1e+05)

### Arguments

`trackName` | A character string, used as track label by igv, we recommend unique names per track.
`quantitativeData` | A polyvalent object, either a data.frame, GRanges, or UCSCBedGraphQuantitative object
`fileFormat` | only "bedGraph" supported at present; wig and bigWig support soon.
`color` | A CSS color name (e.g., "red" or "#FF0000")
`sourceType` | only "file" supported at present ("gcs" for Google Cloud Storage, and "ga4gh" for the Global Alliance API may come)
`autoscale` | Autoscale track to maximum value in view
`min` | Sets the minimum value for the data (y-axis) scale. Usually zero.
`max` | Sets the maximum value for the data (y-axis) scale. This value is ignored if autoscale is TRUE
`visibilityWindow` | Maximum window size in base pairs for which indexed annotations or variants are displayed. Defaults: 1 MB for variants, whole chromosome for other track types.
