To load “SeqinR” R package follow the commands

        > library("seqinr")
                  > leprae <- read.fasta(file = "Q9CD83.fasta")
                  > ulcerans <- read.fasta(file = "A0PQ23.fasta")
                  > lepraeseq <- leprae[[1]]
                  > ulceransseq <- ulcerans[[1]]
                  > lepraeseq # Display the contents of the vector "lepraeseq" 
          

Procedure to work simulator

Follow the code in the command window:

            library("seqinr")   # Load seqinr package in R
                      choosebank("swissprot") # Chossingswissprot for the sequence
                      test_query<- query("leprae", "AC=Q9CD83")
                      lepraeseq<- getSequence(test_query$req[[1]])
                      lepraeseq
                      Click Execute Button for output.
