## prepare input to mapLD function for haplotype block identification

### Description

prepare input to mapLD function for haplotype block identification

### Usage

    snpm2mapLD(x, chrnum, runMAP=TRUE, ...)

### Arguments

`x` | snp.matrix instance
`chrnum` | chromosome number
`runMAP` | logical indicating whether or not to run mapLD
`...` | additional arguments to mapLD

### Details

sets up a data frame suitable for mapLD, and will invoke with appropriate arguments identifying columns for alleles and other identifiers if runMAP is TRUE (default).

smtest is a small snp.matrix instance

### Value

a list with element struc holding the data frame, and mapLD output if requested. Note that mapLD writes an eps file to disk *sigh*.

### Examples

    data(smtest)
    ss = snpm2mapLD(smtest, chrnum=20, runMAP=FALSE)
    ss
    # you could run mapLD on ss[[1]]
