cran - Package dependencies when installing from source in R

Question

Just confirming: If I distribute my R package as ZIP/TAR then installing the package will not automatically download/install dependencies because I have to set repos = NULL in install.packages() and dependencies parameter is not used if repos = NULL? The way to possibly get this to work is to package an install script. Is that possible? Am I completely missing something here and there is a mechanism to install from source AND automagically download and install dependencies?

Answer 1

The devtools package has a function install. If used on a directory containing the source code for an R package, it will install that package and download any dependencies from CRAN.
