## Flip the orders of markers on a set of chromosomes

### Description

Flip the orders of markers on a specified set of chromosome, so that the markers will be in the reverse order.

### Usage

    flip.order(cross, chr)

### Arguments

`cross` | An object of class `cross`. See `read.cross` for details.
`chr` | Vector indicating the chromosomes to flip. This should be a vector of character strings referring to chromosomes by name. A logical (TRUE/FALSE) vector may also be used.

Results of `est.rf` and `markerlrt` are deleted.
