#Function that converts character arms to numeric


##Input:
### chrom : vector with chromosome numbers corresponding to each character arm
### char.arms : vector containing charcter arms; dentoed p or q

## Output:
### arms : vector with numeric arms calculated as chrom*2 - 1 or chrom*2

##Required by:
### adjustPos
### adjustSeg

### winsorize
### aspcf

##Requires:
###  none
