ffrep.int: Replicate Elements of ff vectors.

Description

Similar as rep.int in the base package but for ff vectors.

Usage

ffrep.int(x, times)

Arguments

x

an integer ff vector

times

integer ff vector giving the (non-negative) number of times to repeat each element if of length length(x), or an integer of length 1 indicating how many times to to repeat the whole vector. Negative or NA values are an error.

Value

• An ff vector of integers where x is recycled

Examples

ffrep.int(ff(1:1000), times=20)
ffrep.int(ff(factor(LETTERS)), times=20)
ffrep.int(ff(Sys.time()), times=20)
ffrep.int(ff(seq.Date(Sys.Date(), Sys.Date()+10, by = "day")), times=20)

x <- ff(factor(LETTERS), length=10000)
ffrep.int(x, times=ff(1:10000))

## Or supply an ff vector of the same length as x
x <- seq.Date(Sys.Date(), Sys.Date()+10, by = "day")
x <- as.ff(x)
ffrep.int(x, times=ff(0:10))

x <- ff(factor(LETTERS), length=10)
ffrep.int(x, times=ff(1:10))
