### Examples

    ## Count the number of droplets in a well.
    aWell <- ddpcrWell(well=KRASdata[["E03"]])
    numDroplets(aWell)

    ## Get all of the wells in a named vector.
    krasPlate <- ddpcrPlate(wells=KRASdata)
    (numberDroplets <- numDroplets(krasPlate))
    sum(numberDroplets)

    ## We can choose to get a subset of the wells.
    (numberDroplets <- numDroplets(krasPlate[c("H03", "A04")]))
    sum(numberDroplets)
