| mutate.Chromosome {galgo} | R Documentation |
Mutates a chromosome in specific positions.
## S3 method for class 'Chromosome': mutate(ch, positions=sample(length(ch), 1), ...)
positions |
Vector of gene positions to be mutated. If positions is a vector of length 1 and the value is less than 1, it is considered as a probability; thus a positions vector is computed using the probability and the chromsome length. |
This method updates the gene values in the chromsome calling the method mutate for all genes indexed by positions vector.
Returns the positions mutated.
