SeqAn Headers for R

Build Status codecov License Docs DOI


This package provides R with access to SeqAn v2.4 header files. SeqAn is an open source C++ library of efficient algorithms and data structures for the analysis of sequences with the focus on biological data.


RSeqAn can be used via the LinkingTo: field in the DESCRIPTION field of an R package. Note that the compiler will need to compile as C++14. This can be done in R as Sys.setenv("PKG_CXXFLAGS"="-std=c++14").

For a quick example, see our introductory vignette. Alternatively you can run the C++ code from the vignette directly by entering

pattern_search("This is an awesome tutorial to get to know SeqAn!", "tutorial")

Don't forget to set the C++14 compiler flags if you do this!


  • We recommend installing the release version through Bioconductor, especially if you are running R on Windows. Instructions are provided on their page.

  • Version 1.3.1 can also be installed through Bioconductor (for now, Bioconductor has a separate release cycle), downloaded as a tagged release, or installed with devtools by running:

devtools::install_github("compbiocore/RSeqAn", ref="v1.3.1")

This version contains Rcpp::as and Rcpp::wrap functions for CharString and is the one submitted to the Journal of Open Source Software.

  • The development version can be installed with devtools by running:
devtools::install_github("compbiocore/RSeqAn", ref="devel")

This version contains additional wrappers, though we cannot guarantee that they will work for you.
