Or have a look at the functions getLD and getLDlarge from the trio package also available on CRAN, which can be used to compute LD values genome-wide. You can also plot the LD matrix, and estimate LD blocks using the function findLDblocks. These functions cannot only be applied to trio data, but were actually implemented for population-based data consisting of independent subjects (see the argument parentsOnly).
