Package: r-cran-matrix
Version: 1.2-13-1
Severity: normal

Hi Dirk,

When I install r-cran-matrix version 1.2-13-1 from unstable, it puts it under 
/usr/lib/R/site-library ,
whereas if I downgrade to version 1.2-12-1 from testing, it puts it under 
/usr/lib/R/library with the
other recommended packages. I am not sure if this was an intentional change, 
but it breaks R CMD check
for packages that have Matrix in the Imports line of their DESCRIPTION file. 
Specifically, if you call
R CMD check on a package that is downstream of Matrix, then when it gets to 
examples or tests, it says:

Error: package or namespace load failed for 'rstanarm' in loadNamespace(j <- 
i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called 'Matrix'

I put in a print statement right before that, which outputs

  > library(testthat)
  > print(.libPaths())
  [1] "/tmp/RtmpKN7neI/RLIBS_8051142d41b" "/usr/lib/R/library"               
  > library(rstanarm)

so it seems that R CMD check does not copy Matrix into /tmp/Rtmp* because it 
assumes it is already in
/usr/lib/R/library, which is not the case anymore.

Not a big deal since I have to do R CMD check on r-devel anyway.
