Mutates a chromosome in specific positions.

1 2	## 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.

   mutate(cr) # mutate 1 gene randomly
   cr
   mutate(cr,1:3) # mutate genes 1, 2, and 3
