You'll need AllelicImbalance and VariantAnnotation from Bioconductor. The AllelicImbalance package provides a small but informative dataset of three SNPs on Chromosome 17 of the hg19 build of the human genome. The files have been extracted into this book's data repository in datasets/ch1/allele_expression .
