I love exploratory data analysis. Over the years it proved invaluable first in my degree work (I owe my degree to it) and later in my professional research. Fancy analysis---and R would be a great tool---can come later, but always start with plots to get a feel for the problem at hand. I'm shooting for a histogram plot by this weekend.
