# List all available methods for getLength generic function:
#
   methods(getLength)
#
# Example with seven DNA sequences from a FASTA file:
#
  ff <- system.file("sequences/someORF.fsa", package = "seqinr")
  fs <- read.fasta(file = ff)
  stopifnot(all(getLength(fs) == c(5573, 5825, 2987, 3929, 2648, 2597, 2780)))
#
# Example with 49 sequences from an ACNUC server:
#
  ## Not run: 
  # Need internet connection
  choosebank("emblTP")
  fc <- query("fc", "sp=felis catus et t=cds et o=mitochondrion")
  getLength(fc)
  closebank()  

## End(Not run)
