R use ifelse to replicate

I want to use ifelse to replicate my data.
data here:

type     Time          value
A        2015-01-01    100
A        2016-05-01    200
B        2015-12-01    150
B        2016-12-01    300

The result I want is like:

type     Time          value
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2015-01-01    100
A        2016-05-01    200
A        2016-05-01    200
A        2016-05-01    200
A        2016-05-01    200
A        2016-05-01    200
A        2016-05-01    200
A        2016-05-01    200
A        2016-05-01    200
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150
B        2015-12-01    150    
B        2016-12-01    300

My code:

library(readxl)
library(lubridate)
library(data.table)
data <- read_excel("data.xlsx")
data <- as.data.table(data)
data[,Time:=as.Date(Time,"%Y/%m/%d")]
result <- data[ifelse(year(Time)==2016,rep(1:.N,12-month(Time)+1),rep(1:.N,13))]

However, it is flase.
I think the problem is I cannot use .N. How to solve this?
Thanks.
