Querying On-line Resources
Many different meta-data resources are available on-line, and several of these provide a Web services model for interactions. R and Bioconductor support the use of different technologies (including HTTP, SOAP, and XML-RPC) for accessing different Web services. In this chapter we describe the tools for accessing Web services and demonstrate their use in a number of examples.
Our view is very similar to that proposed by Stein (2002), who emphasized Web services as the basic computational resource for bioinformatics. Well-designed Web services will play an essential role in solving many bioinformatic problems and R has the capability of playing many different roles, both on the client and the server side.
