The seqinR package for the R environment is a library of utilities to retrieve and analyze biological sequences. It provides an interface between: (i) the R language and environment for statistical computing and graphics, and (ii) the ACNUC sequence retrieval system for nucleotide and protein sequence databases such as GenBank, EMBL, SWISS-PROT. ACNUC is very efficient in providing direct access to subsequences of biological interest (e.g., protein coding regions, tRNA, or rRNA coding regions) present in GenBank and in EMBL. Thanks to a simple query language, it is then easy under R to select sequences of interest and then use all the power of the R environment to analyze them. The ACNUC databases can be locally installed but they are more conveniently accessed through a web server to take advantage of centralized daily updates. The aim of this chapter is to provide a handout on basic sequence analyses under seqinR with a special focus on multivariate methods.
