mpMap2 (version 1.0.0)

generateGridPositions: Specify an equally spaced grid of genetic positions

Description

Specify an equally spaced grid of genetic positions

Usage

generateGridPositions(spacing)

Arguments

spacing

The spacing of the genetic positions, in cM.

Value

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

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.

Examples

# NOT RUN {
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))
# }
