Does anyone have advice on how to instruct R CMD check to use a
non-standard set of libraries? Here's the situation:
I'm trying to do some automated checking on package dependencies of a
package I maintain. In order to do that I've written code that takes
the list of the dependent packages and for each package (1) downloads
the most recent/available .tar.gz file; (2) installs the "Suggests:" and
"Depends:" packages for the package that are not already installed; (3)
runs R CMD check and stores the output.
I wanted to do this in a way that would not necessarily bloat my base
installation, so I wanted to do step #2 into a new library. Once I've
figured out what the missing dependencies are (depMiss), I
install.packages(depMiss,lib=libdir)
Then I run R CMD check as follows.
ss <- suppressWarnings(system(
paste("export R_LIBS=./library; R CMD check",
file.path(tarballdir,tn)),
intern=TRUE))
However, this only seems to work partially. It does prevent the check
from failing with an error that the package doesn't exist: *BUT* when
the examples are actually run, I get results like this (this is from the
'agridat' package, which "Suggests:" the hglm package, which has hence
been installed in the 'libdir' directory).
[168] "168: Loading required package: hglm"
[169] "169: Warning in library(package, lib.loc = lib.loc,
character.only = TRUE, logical.return = TRUE, :"
[170] "170: there is no package called ‘hglm’"
Checking installed.packages() shows that hglm is indeed installed in
the appropriate directory. agridat "Suggests:" hglm. The
"crowder.germination" example in agridat tries require(hglm) and fails;
it therefore doesn't fit the relevant HGLM model -- when the example
tries to reference this model a few lines later, the example fails.
Admittedly this could be seen as a bug in the example (it shouldn't try
to access a model it knows it can't fit), but I wonder if there's a way
I can get the examples run to see the non-standard package location.
I could (I guess) modify my .Rprofile temporarily ... ? But I'm
curious if there's a right way to do this ...
thanks
