Forgive the really naive questions, but my C/C++ and Biostrings skills
are pretty rough. I have been playing with Rcpp to interface to an
external library for reading sequence formats. I am reading DNA
sequences one-at-a-time and would like to package a set of those up as a
DNAStringSet. I have at least two options:
1) Return a character vector back to R and then create a DNAStringSet in
R. This works now and works fine.
2) Create the DNAStringSet in the cpp code.
Are there advantages to using choice #2? If so, where would I start to
get the necessary Rcpp/Biostrings glue in place? I know how to make new
S4 objects in Rcpp, so it is really a question of knowing what class
hierarchy I need to instantiate and, roughly, how. Any pointers or code
examples?
Thanks,
Sean
