                mo = (rep(seq(as.Date('2014-1-1'),
                              length.out = 24,
                              by = 'month'),
                          4)),
                n = rbinom(4 * 24, 100, 0.5),
                d = round(runif(4 * 24, 90, 110)),
                g1 = rep(c('a', 'b'), each = 48),
                g2 = rep(c('A', 'B'), each = 24))
