inject_letter_random: Inject a letter in a set of sequences at random positions

In FastqCleaner: A Shiny Application for Quality Control, Filtering and Trimming of FASTQ Files

Description

Inject a letter in a set of sequences at random positions

Usage

inject_letter_random(my_seq, how_many_seqs = NULL,
  how_many_letters = NULL, letter = "N")

Arguments

my_seq	character vector with sequences to inject
how_many_seqs	How many sequences pick to inject Ns. An interval [min_s, max_s] with min_s minimum and max_s maximum sequences can be passed. In this case, a value is picked from the interval. If NULL, a random value within the interval [1, length(my_seq)] is picked.
how_many_letters	How many times inject the letter in the i sequences that are going to be injected. An interval [min_i max_i] can be passed. In this case, a value is randomly picked for each sequence i. This value represents the number of times that the letter will be injected in the sequence i. If NULL, a random value within the interval [1, width(my_seq[i])] is picked for each sequence i.
letter	Letter to inject. Default: 'N'

Value

character vector

Examples

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

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

set.seed(10)
s <- inject_letter_random(s, how_many_seqs = 1:30, how_many= 2:10)
