as.mapframe: Convert object to 'mapframe'.

In gact/shmootl: QTL Analysis Utilities for Yeast

Description

Convert object to mapframe.

Usage

as.mapframe(from, map.unit = NULL)

## S3 method for class 'data.frame'
as.mapframe(from, map.unit = NULL)

## S3 method for class 'list'
as.mapframe(from, map.unit = NULL)

## S3 method for class 'map'
as.mapframe(from, map.unit = NULL)

## S3 method for class 'mapframe'
as.mapframe(from, map.unit = NULL)

## S3 method for class 'scanone'
as.mapframe(from, map.unit = NULL)

Arguments

from	Object containing map data.
map.unit	Explicitly sets 'map.unit' attribute. This must be specified if an object does not have an existing 'map.unit' attribute.

Value

A mapframe corresponding to the input object.

Mapframe

A mapframe object is a class of data.frame that contains mapped information, or a data.frame with equivalent properties. The leftmost two columns of every mapframe object must be as follows:

• chr: Chromosome/sequence labels in the order defined for the current reference genome.

• pos: Map positions in increasing order within each chromosome/sequence. The map unit used in a mapframe position column must be indicated by setting its 'map.unit' attribute.

Any number of additional data columns can be included. If present, the row names indicate the locus IDs, which should be unique within the given mapframe.
