I installed the GeneGA package but got an error message while trying the example: 

seqfile = system.file("sequence", "EGFP.fasta", package="GeneGA")
seq = unlist(getSequence(read.fasta(seqfile), as.string=TRUE))
GeneGA.result = GeneGA(sequence=seq, popSize=40, iters=100, crossoverRate=0.3, mutationChance=0.05, region=c(1,60))

This is the error message I get after the GeneGA.result:

The current generation is: 1 
Error in index02:index01 : argument of length 0


Someone else experienced a similar error while playing with the example (GeneGA Error Message). Does anyone know how to fix this error?

And here is my session Info.
