Dear developeRs,

I've searched the documentation, FAQ, and mailing lists, but haven't
found the answer(*) to the following:

When should one specify LazyLoad, LazyData, and ZipData?

Preferably always, and I would suggest all should be 'yes' if your package will work with them.

And what is the default if they are left unspecified?

It varies by R version and platform.  But as a guide

LazyLoad: yes for all but small packages (those with less than
  25Kb of R code)
LazyData: no
ZipData: yes on Windows if there is more than 100Kb of data and no
  duplicate namestems (e.g. foo.R and foo.tab).

(*)Except that
1) If the package you are writing uses the methods package, specify
LazyLoad: yes, and
2) The optional ZipData field controls whether the automatic Windows
build will zip up the data directory or no: set this to no if your
package will not work with a zipped data directory.
