Multiple sequence alignment with R I want to incorporate Multiple sequence alignment into our Shiny app, i.e. allow the possibility of selecting different nucleotide sequences, and do a multiple sequence alignment in real-time. The user would define as input different nt. sequences and then a tree will pop up in the app. Do you think this is feasible?

Any recommendations and feedback are really appreciated :)
The ‹msa› package on Bioconductor does exactly that.

It doesn’t hand the results on a silver platter, though: you’ll need to read the vignette carefully to learn how to use it. But after that it’s pretty powerful.
