random_qual {FastqCleaner} | R Documentation

## Create random qualities for a given encoding

### Description

Create a `BStringSet` object with random qualities

### Usage

    random_qual(slength, swidth, qual = NULL, encod = c("Sanger",
      "Illumina1.8", "Illumina1.5", "Illumina1.3", "Solexa"), prob = NULL)

### Arguments

`slength` | number of sequences
`swidth` | width of the sequences
`qual` | quality range for the sequences. It must be a range included in the selected encoding: 'Sanger' = [0, 40] 'Illumina1.8' = [0, 41] 'Illumina1.5' = [0, 40] 'Illumina1.3' = [3, 40] 'Solexa' = [-5, 40] example: for a range from 20 to 30 in Sanger encoding, pass the argument = c(20, 30)
`encod` | sequence encoding
`prob` | a vector of range = range(qual), with probabilities to set the frequency of each quality value. Default is equiprobability. If the sum of the probabilities is > 1, the values will be nomalized to the range [0, 1].

### Value

`BStringSet` object
