Perhaps I misunderstand, but ?chisq.test explicitly says: "If x is a matrix with at least two rows and columns, it is taken as a two-dimensional contingency table: the entries of x must be non-negative integers. Otherwise, x and y must be vectors or factors of the same length; cases with missing values are removed, the objects are coerced to factors, and the contingency table is computed from these. Then Pearson's chi-squared test is performed of the null hypothesis that the joint distribution of the cell counts in a 2-dimensional contingency table is the product of the row and column marginals."
Moreover, expected counts are one component of the returned result (see the "value" section). Proportions can of course easily then be obtained if so desired.
