You don't appear to be using any functionality from the date package but are using the "Date" class which is built into the base of R. Assuming:

d <- as.Date("03/11/05", "%m/%d/%y")

# and try one of these:

d3 <- structure(rep(NA, 3), class = "Date") d3[1] <- d
d3

# or

d3 <- rep(d, 3) + NA
d3[1] <- d
d3

# or

d3 <- rep(NA, 3)
class(d3) <- "Date"
d3[1] <- d
d3

# or

d3 <- vector(length = 3, mode = "numeric") + NA class(d3) <- "Date"
d3[1] <- d
d3
