Thanks I meant Imports,  just wasn't thinking.  The main issue was how deep to 
recurse.

Only rerddap, and ideally in Imports rather than Depends.

2017-08-29 Thread Dason Kurkiewicz 
You just need to list the packages that you explicitly depend on.
Most likely you should be using imports instead of "depends" but
that's a different issue.  It might seem like you're doing the user a
favor by making it explicit *all* the packages that will end up on
their system if your package is installed but what happens when a
package you use changes the packages that it depends on?  Are you
going to take the time to check n layers deep to make sure your
dependency list matches what should be on the users system?  If a
package you use drops one of the other packages that they used to
import in favor of a different package and you don't notice it then
you're going to end up installing a package on the user's system that
they don't actually need.

tldr: Just list the packages you explicitly need.

[R-pkg-devel] In Description file, how far removed should the depends go?

2017-08-29 Thread Roy Mendelssohn - NOAA Federal 
HI All:

What is best practice for the "depends" in the Description file,  in terms of 
how of how many layers down do I list depends?  For example,  if my package 
depends on the rerddap package,  is it best practice  to just list rerddap in 
the depends,  or should I also list all the packages rerddap depends on  - 
which can go many layers deep.  What is best practice for this?

Thanks,

-Roy
