Hi r-devels,

may I ask for an enhancement for download.packages() to optionally resolve package dependencies similarly to the respective functionality in install.packages() ?

This would be a major help in compiling a large number of packages (e.g. by means of download.view() from pkg ctv) for later offline installations.

Last November, I addressed Duncan Murdoch offline in this issue, and Duncan then seconded me---so the idea might not be this silly. He was pointing me to available.packages() which already provides a dependency list, which though would have to be parsed.

AFAICS in the svn, as of rev54842, he has not found the time for looking deeper into this so far. Surely, like most of you, he has had more urgent issues to work on, but maybe someone (else) of you has an idea for an easy but still sustainable solution.

Any suggestions appreciated.
