qtl.heatmap {DOQTL} | R Documentation

## Plot a Heatmap of all QTL

### Description

This function accepts LOD scores and SNP locations and plots a heatmap of the QTL. Each QTL is scaled to between 0 and 1 and the QTL are hierarchically clustered. A tile plot is then created with QTL colored from white (strong) to black (weak). The motivation for this plot is to visualize QTL that may be coincident across different phenotypes.

### Usage

      qtl.heatmap(lod, ...)

### Arguments

`lod` | Data frame, containing the SNP names, chromosome an dbp locations in columns 1 through 3 and LOD scores for all phenotyped in the remaining columns.
`...` | Additional arguments to be passed to plot.

### Value

No value is returned. A tile plot is plotted from the data.

### Note

The QTL the appear in white are *not* neccessarily signficant. They are simply the strongest QTL for each phenotype.
