Description Usage Arguments Details Value Author(s) Examples

makeMSEAPackage is a method that generates a package that will load an appropriate MSEADb object that will in turn point to existing annotation packages.

makeMSEAPackage(
    pkgname,
    data,
    metadata,
    organism,
    version,
    maintainer,
    author,
    destDir,
    license = "Artistic-2.0"
)

`pkgname`	What is the desired package name.
`data`	Data frame contains PathBankID, PathwayName, PathwaySubject, MetaboliteID, MetaboliteName, HMDBID, KEGGID, ChEBIID, DrugBankID, CAS, Formula, IUPAC, SMILES, InChI, and InChIKey
`metadata`	Data frame contains metadata of the package
`organism`	The name of the organism this package represents
`version`	What is the version number for this package?
`maintainer`	Who is the package maintainer? (must include email to be valid)
`author`	Who is the creator of this package?
`destDir`	A path where the package source should be assembled.
`license`	What is the license (and it's version)

The purpose of this method is to create a special package that will depend on existing annotation packages and which will load a special MSEADb object that will allow proper dispatch of special select methods. These methods will allow the user to easily query across multiple annotation resources via information contained by the MSEADb object. Because the end result will be a package that treats all the data mapped together as a single source, the user is encouraged to take extra care to ensure that the different packages used are from the same build etc.

A special package to load an MSEADb object.
