## Plot a phenotype distribution

### Description

Plots a histogram or barplot of the data for a phenotype from an experimental cross.

### Usage

    plotPheno(x, pheno.col=1, ...)

### Arguments

`x` | An object of class `cross`. See `read.cross` for details.
`pheno.col` | The phenotype column to plot: a numeric index, or the phenotype name as a character string. Alternatively, one may give a numeric vector of phenotypes, in which case it must have the length equal to the number of individuals in the cross, and there must be either non-integers or values < 1 or > no. phenotypes; this last case may be useful for studying transformations.
`...` | Passed to `hist` or `barplot`.

### Details

Numeric phenotypes are displayed as histograms with approximately 2 sqrt(n) bins. Phenotypes that are factors or that have very few unique values are displayed as barplots.

### Value

None.
