Tile an array

Tile an array

rray_tile(x, times)

Arguments

x	A vector, matrix, array or rray.
times	An integer vector. The number of times to repeat the array along an axis.

Value

x with dimensions repeated as described by times.

Details

rray_tile() should not be used as a replacement for rray_broadcast(), as it is generally less efficient.

Examples

x <- matrix(1:5)

# Repeat the rows twice
rray_tile(x, 2)
#>       [,1]
#>  [1,]    1
#>  [2,]    2
#>  [3,]    3
#>  [4,]    4
#>  [5,]    5
#>  [6,]    1
#>  [7,]    2
#>  [8,]    3
#>  [9,]    4
#> [10,]    5

# Repeat the rows twice and the columns three times
rray_tile(x, c(2, 3))
#>       [,1] [,2] [,3]
#>  [1,]    1    1    1
#>  [2,]    2    2    2
#>  [3,]    3    3    3
#>  [4,]    4    4    4
#>  [5,]    5    5    5

#>  [8,]    3    3    3
#>  [9,]    4    4    4
#> [10,]    5    5    5
