getSequence: Generic function to get sequence data

In seqinr: Biological Sequences Retrieval and Analysis

Generic function to get sequence data

Description

getSequence returns the sequence either as vector of single chararacters or as a single string of multiple characters.

Usage

getSequence(object, as.string = FALSE, ...)
## S3 method for class 'SeqAcnucWeb'
getSequence(object, as.string = FALSE, ..., socket = autosocket())

Arguments

object	an object of the class SeqAcnucWeb or SeqFastadna, or SeqFastaAA or SeqFrag or a list of these objects, or an object of class qaw created by query
as.string	if TRUE sequences are returned as strings of multiple characters instead of a vector of single characters
socket	an object of class sockconn connecting to a remote ACNUC database (default is a socket to the last opened database).
...	further arguments passed to or from other methods

Value

For a single sequence an object of class character containing the characters of the sequence, either of length 1 when as.string is TRUE, or of the length of the sequence when as.string is FALSE. For many sequences, a list of these.
