Documentation for SLiM function nucleotideFrequencies, which is a method of the SLiM class SLiMBuiltin. Note that the R function is a stub, it does not do anything in R (except bring up this documentation). It will only do anything useful when used inside a slim_block function further nested in a slim_script function call, where it will be translated into valid SLiM code as part of a full SLiM script.

nucleotideFrequencies(sequence)

Arguments

sequence

An object of type integer or string. See details for description.

Value

An object of type float.

Details

Documentation for this function can be found in the official SLiM manual: page 749.

A convenience function that returns a float vector of length four, providing the frequencies of occurrences of A / C / G / T nucleotides, respectively, in the supplied nucleotide sequence. The parameter sequence may be a singleton string (e.g., "TATA"), a string vector of single characters 0 α α α α 0 α α α α 0 α α α α 0 0 β α β β 0 β α α β 0 β β α β 0 (e.g., "T", "A", "T", "A"), or an integer vector (e.g., 3, 0, 3, 0), using SLiM's standard code of A=0, C=1, G=2, T=3.
