[BioC] building annotation package for porcine

[Marc Carlson]

Hi Javier,

You are VERY close.  The main trouble is that your schema is the wrong
kind.  You want to use a chip schema (PIGCHIP_DB) because you are making
a chip package.  The other kind of schema (PIG_DB, HUMAN_DB etc.) is
reserved for making org packages, and we already make those for you.

Here is what I used (note that the outputDir is for unix):


makeDBPackage("PIGCHIP_DB",
affy=TRUE,
prefix="Porcine",
fileName="Porcine.na30.annot.csv",
baseMapType="gbNRef",
outputDir = ".",
version="1.0.0",
manufacturer = "Affymetrix",
chipName = "Porcine",
manufacturerUrl = "http://www.affymetrix.com")

This should create a source directory for you called Porcine.db  Once
you have the source directory, you should be able to build, check and
install it as with any other source package for R.


  Marc
