It appears that strataG doesn’t work with the latest version of R (v 3.5.3). I did, however, realize that it’s possible to do the analysis using pegas. You use the same command to read a FASTA file in as I showed in the notes. Then you run tajima.test(seqs) on the results (where seqs is the name of the object you read the DNA sequence information into). I’ll update the project assignment to show the new syntax later today.
