Problem loading my multifasta

Hello All,

I have problem loading my multifasta and running rhierbaps. I I can see that the fasta.file.name is empty.

ibrary(rhierbaps)
fasta.file.name <- “clean_hlr.fasta”
fasta.file.name <- system.file(“extdata”, “clean_hlr.fasta”, package = “rhierbaps”)
fasta.file.name
[1] “”
snp.matrix <- load_fasta(fasta.file.name)
Error in load_fasta(fasta.file.name) :
Invalid msa or the file does not exist!
How do I have to
