sager_rids() is used internally to keep track of the resource
names (rname) in the package's cache. It is used in functions
such as sagerQuantData(), ... that return the path to a
resource (rpath). When new data are added to the cache, their
rname should be added here.
sager_urls() keeps track of the resource URLs on zenodo. It is
used in sagerAddData() the get the URLs of the resources to be
added.
Both return named vectors.
sager_rids(which = c("quant", "id", "mzml", "config"))character() specifying what type of resource to
return. One or multiple of "quant", "id" and "mzml".
ChangeLog:
version 2: updated 'subset' data files and new config file
version 3: provide 3 separate subsetted mzML files, and update quant and id files (generated from re-running sage on the mzML subsets).
version 4: udpate subset files, and remove the prefix from three subsetted mzML files.
