extract_random_seqs_from_genome | R Documentation |
This function allows users to specify a number of sequences of a specified length that shall be randomly sampled from the genome. The sampling rule is as follows: For each locus independently sample:
1) choose randomly (equal probability: see sample.int
for details) from which of the given chromosomes the locus shall be sampled (replace = TRUE
).
2) choose randomly (equal probability: see sample.int
for details) from which strand (plus or minus) the locus shall be sampled (replace = TRUE
).
3) randomly choose (equal probability: see sample.int
the starting position of the locus in the sampled chromosome and strand (replace = TRUE
).
