Subject: [Rd]  Size of (objects in) sysdata.rda
Message-ID: <22676784.post@talk.nabble.com>


Dear all,

in my package FrF2, I currently face a trade-off of object size and
calculation run times. I would like to work with catalogues with some
pre-calculated information, and calculate some other information on an
as-needed basis. 

Is there any experience as to what sizes of objects in sysdata.rda will make
a package difficult to handle / slow ? If I would put into the catalogues
what I currently consider useful, I would most likely end up with an rda
file that takes more than 30 seconds to load on my machine. With the current
structure, it would consist almost exclusively of one massive list. I
suspect that this is not very wise. Would it help to lazy-load data and
split the list into several smaller ones (the larger ones of which will not
be used all that often) ? 
Or do I need a different strategy altogether ? 

Thanks for any advice!

Regards, Ulrike
