plot {trigger} | R Documentation

## Graphical Display of Trigger Analysis

### Description

Graphical display of genomewide linkage map, multi-locus linkage or eQTL variation

### Usage

    	## S4 method for signature 'trigger,missing'
    plot(x,y,type = c("link", "mlink", "eqtl"),
    				cutoff  = 3.3e-4, qcut = 0.1, bin.size = NULL)

### Arguments

`x` | An object of class `trigger`.
`y` | Ignore option, not used.
`type` | An argument describing the type of plot. Select from `link` (default) for genome-wide linkage map, `eqtl.R2` for graphical display of eQTL-R^2 contribution or `mlink` for display of genome-wide epistasis effect.
`cutoff` | Threshold value for `link`. The measures below the threshold are called significant and are plotted.
`qcut` | Q-value threshold for `mlink`. The joint multi-locus linkage probabilities with q-values below the threshold are called significant and are plotted.
`bin.size` | Optional for `mlink`. If not `NULL`, each chromosome will be divided into several bins, each with size `bin.size`. Markers within a bin will be considered as at a same position.
