generateGridPositions: Specify an equally spaced grid of genetic positions

In mpMap2: Genetic Analysis of Multi-Parent Recombinant Inbred Lines

Description

Specify an equally spaced grid of genetic positions

Usage

generateGridPositions(spacing)

Arguments

spacing

The spacing of the genetic positions, in cM.

Details

Some functions, such as imputeFounders and computeGenotypeProbabilities, take in a set of genetic positions as one of the inputs. This function is an easy way to specify an equally spaced grid of positions.

Note that the return value is itself a function, which is applied internally by imputeFounders or computeGenotypeProbabilities to an object of class mpcrossMapped.

Value

A function which can be applied to an object of class mpcrossMapped by imputeFounders or computeGenotypeProbabilities.

Examples

data(simulatedFourParentData)
#Create object that includes the correct map
mapped <- new("mpcrossMapped", simulatedFourParentData, map = simulatedFourParentMap)
#Estimate IBD genotypes at all the markers, and marker midpoints
imputed <- imputeFounders(mapped, errorProb = 0.02, 
	extraPositions = generateGridPositions(1))
