coefplot {DOQTL} | R Documentation

## Plot the QTL model coefficients

### Description

Given a DOQTL object, plot the founder allele coefficients on one chromosome. The coefficients are centered around zero before plotting.

### Usage

      coefplot(doqtl, chr = 1, stat.name = "LOD", conf.int = TRUE, legend = TRUE,
      colors = "DO", sex, ...)

### Arguments

`doqtl` | A DOQTL object as produced by `scanone`. A list containing two elements: lod and coef.
`chr` | Character containing the chromosome to plot.
`stat.name` | Character string containing the name of the mapping statistic.
`conf.int` | Boolean that is TRUE if the QTL support interval should be shaded in the plot. Default = TRUE.
`legend` | Boolean that is TRUE if the color legend for the DO founders should be drawn. Default = TRUE.
`colors` | Either "DO", in which case DO colors are supplied or a data.frame with three columns containing the founder letter code, founder strain name and founder color in columns 1:3.
`sex` | Character that is either FALSE or M, indicating the sex to use. Only used on X chromosome.
`...` | Additional arguments to be passed to plot.

### Value

No value is returned. A plot with the founder coefficients in the top panel and the LOD score in the bottom panel is drawn.
