Description
Hi,
packrat has an issue with the package survival. survival depends on splines which is no longer on CRAN as a separate download. So when I depend on survival in a project I get the error in the subject.
That is even true when I use extlib:
> packrat::extlib("splines")
Error in library(package, character.only = TRUE, lib.loc = lib.loc) :
‘splines’ is not a valid installed package
I use the current packrat from CRAN

Research direction
Start by reproducing the reported failure with packrat::extlib("splines") and the survival dependency. Inspect packrat's handling of R packages that are no longer separate CRAN downloads. Done means survival can be depended on and splines can be loaded without the reported invalid-installed-package error.
