## Create random sequences

### Description

Create a `DNAStringSet` object with random sequences

### Usage

    random_seq(slength, swidth, nuc = c("DNA", "RNA"), prob = c(0.25, 0.25,
    0.25, 0.25))

### Arguments

`slength` | Number of sequences
`swidth` | Width of the sequences
`nuc` | Create sequences of DNA (nucleotides = c('A', 'C', 'G', 'T')) or RNA (nucleotides = c('A, 'C', 'G', 'U'))?. Default: 'DNA'
`prob` | A vector of four probability values used to set the frequency of the nucleotides 'A', 'C', 'G', 'T', for DNA, or 'A', 'C', 'G', 'U', for RNA. For example = c(0.25, 0.25, 0.5, 0). Default is = c(0.25, 0.25, 0.25, 0.25) (equiprobability for the 4 bases). If the sum of the probabilities is > 1, the values will be nomalized to the range [0, 1].

### Value

`DNAStringSet` object

### Examples

    # For reproducible examples, make a call to set.seed before
    # running each random function

    set.seed(10)
    s1 <- random_seq(slength = 10, swidth = 20)
    s1

    set.seed(10)
    s2 <- random_seq(slength = 10, swidth = 20,
    prob = c(0.6, 0.1, 0.3, 0))
    s2
