T.test from summary statistics in R?

Question

In R prop.test can take a table of summary statistics (the number of cells from cross tabulation) instead of all the data (see parameter x here ):

x is the vector of success counters, a one-dimensional table with two records, or a two-dimensional table (or matrix) with 2 columns, giving counts of successes and failures , respectively.

Is there a way to give t.test (or some equivalent function) a summary of the mean, standard deviation and group size for two groups and perform the corresponding calculations?
