This function is a wrapper around rbinom to generate bit vectors. The matrix and array version are creating by row.
Arguments
- size
The size of the vector. Can be a list of dimensions to create a vector, matrix or array. If a vector larger than 3 is provided, each value is treated as the probability of obtaining 1 and a vector of bits is generated using a binomial distribution.
- p
Probability of obtaining a 1. By default it's
0.5.- ...
Extra arguments passed to matrix or array
Examples
## Unbiased probabilities
rbits(10)
#> [1] 1 1 1 0 0 0 1 0 0 0
## Biased probabilities
rbits(10, p = 0.8)
#> [1] 1 1 1 0 1 1 1 1 1 1
## Matrix of bits
rbits(c(3, 4))
#> [,1] [,2] [,3] [,4]
#> [1,] 0 0 0 0
#> [2,] 1 1 1 1
#> [3,] 1 0 0 0
## 3D Array of bits
