[R] SpectrumBackground

[William Dunlap]

I think you can get yourself going by calling
   Peaks:::.First.lib(dirname(find.package("Peaks")), "Peaks")
to get Peaks' DLL loaded.  .First.lib is not getting called.

You should ask the package's maintainer, maintainer("Peaks"), to fix
up the statup procedures.  It the help files had examples or the
package had any tests I think this would have been caught by CRAN.  It
does have two demo's, which do not work for the same reason.
