Create a
DNAStringSet
object
with random sequences
random_seq(slength, swidth, nuc = c("DNA", "RNA"), prob = c(0.25, 0.25, 0.25, 0.25))
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]. |
