Transparent caching of CRAN package files - WORK IN PROGRESS!

I tracked a problem down to this bit of code in get_cache_dir_for_file(file):

  which <- if (grepl("\\.zip$", file)) {
    if (.Platform$pkgType == "win.binary") {
      "platform"
    }

  } else if (grepl("\\.tgz$", file)) {
    if (grepl("^mac.binary", .Platform$pkgType)) {
      "platform"
    }

  } else if (grepl("\\.tar\\.gz$", file)) {
    ## This also includes non-standard (Linux, Solaris, etc.) binaries
    "source"
  }

  get_cache_package_dirs()[[paste0(prefix, which)]]

If the argument file is a string like ".../reshape2_1.4.3.tgz" and .Platform$pkgType is "source", then I'm ending up with which equal to NULL. So at the end of the function, it's trying to do get_cache_package_dirs()[["cran/"]], but that's not a valid key, so I get this error:

Error in get_cache_package_dirs()[[paste0(prefix, which)]] : 
  subscript out of bounds

The names of get_cache_package_dirs() are:

Browse[8]> names(get_cache_package_dirs())
[1] "cran-bin/source"  "cran/platform"    "cran/source"      "bioc-bin/source" 
[5] "bioc/platform"    "bioc/source"      "other-bin/source" "other/platform"  
[9] "other/source"

It looks like there are several paths through the which assignment code that result in NULL.

The consequence of this is that the requested package does get installed, but if I run the same install_packages('pkgname') command again, neither the binary nor the source are found in the cache.
