How to find the package of a class given classname?
For example, there is a class called GAlignments, I want to do something
like
attr("GAlignments", "package") that gives you the package where the class
is defined? But of course, attr("GAlignments", "package") won't work...
You didn't say whether you wanted to be able to do this
programmatically.
If that's the case maybe you're lucky and the package where the class
is defined is already attached to your session. In that case:
> attr(class(new("GAlignments")), "package")
[1] "GenomicRanges"
Otherwise, if the package in question is installed but not attached
you can still do:
??`GAlignments-class`
If the package is not installed but you have a vague idea that this
could be a Bioconductor container, then search the bioconductor
mailing list:
http://bioconductor.org/help/mailing-list/
If that still doesn't give you the answer, then you're welcome to ask
on the list.
Cheers,
H.
PS: If you're using the current devel version of BioC (requires R devel)
the GAlignments class has moved to the new GenomicAlignments package.
Thanks for any help!
