Building R package: "No man pages found in package"

Question

My previously-functioning R package lllcrc recently broke, so I tweaked it, and now I'm having trouble building it again because it acts like it can't see my documentation files:

R CMD INSTALL lllcrc
* installing to library ‘/home/[...]/3.1’
* installing *source* package ‘lllcrc’ ...
** R
** preparing package for lazy loading
** help
No man pages found in package  ‘lllcrc’ 
*** installing help indices
** building package indices
** testing if installed package can be loaded
* DONE (lllcrc)

This is totally weird because I definitely have a complete set of .Rd files in the man folder; in fact, I generated all of these using roxygen2, and all of this worked previously. The R CMD INSTALL even works enough so that the package actually installs and all of its examples run. But documentation is missing. Running ?foo just gives a "no documentation" message.

Another thing: R CMD Rd2pdf lllcrc generates the .pdf documentation as I would expect.

Any ideas?

I just had the same error message ... if you are using roxygen and RStudio then your problem might be the same. The reason became apparent when looking at "Configure build tools" in the "Build" drop-down menu: you need to tick the checkbox "Generate documentation with Roxygen". After that, everything worked.
