**Repeats**

- Command rep is used to replicates the values in a vector.
- Syntax rep (x) replicates the values in a vector x.
- rep (x, times=n ) # Repeat x as a whole n times
- rep (x, each=n ) # Repeat each cell n times

rep { base }

Replicate Element of Vectors and Lists

**Description**

rep replicates the values in x. It is generic function, and the (internal) default method is described here.

rep.int and rep-len are faster simplified versions for two common cases.

They are not generic.

**Usage**

rep (x, ......)

rep.int (x, times)

rep_len (x, length.out)

**The command rep**

**Repeat an object n-times:**

> rep (3.5, times = 10)

[1] 3.5 3.5 3.5 3.5 3.5 3.5 3.5 3.5 3.5 3.5

> rep ( 1 :4, 2)

[1] 1 2 3 4 1 2 3 4

**Repeat an object n-times**

rep (x, times = n)

**Repeat each cell n-times:**

rep (x, each = n)

> x <- 1 : 3

> x

[1] 1 2 3

> rep (x, times = 3)

[1] 1 2 3 1 2 3 1 2 3

> rep (x, each = 3 )

[1] 1 1 1 2 2 2 3 3 3

**Every object is repeated several times successively:**

> rep (1 : 4, each = 2)

[1] 1 1 2 2 3 3 4 4

> rep ( 1 : 4, each = 2 , times = 3)

[1] 1 1 2 2 3 3 4 4 1 1 2 2 3 3 4 4 1 1 2 2 3 3 4 4

**Every object is repeated a different number of times:**

> rep (1 : 4, 2 : 5)

[1] 1 1 2 2 2 3 3 3 3 4 4 4 4 4
