Folks:
My package gdalUtils is a wrapper for a set of binaries on disk (the GDAL
Utilities) -- these have about as many places to install as there are people
installing it, and the system environment variables aren't always much help
(they aren't always set) for locating them. My package is trying to
dummy-proof the usage as much as possible, so one of the things it does is if
it can't find the install, it goes search for the install in, first, standard
locations and runs a short test to see if the install is valid and, if not,
goes on a longer hunt. Right now, it does this search everytime someone boots
up R and uses it, which slows down the process.
What I'm wondering is twofold:
1) Are there any packages/methods by which user "preferences" are saved that
don't require saving workspaces (e.g. does R have a standardized "preferences"
location that packages can use).
2) If the answer to #1 is "no", what is the preferred method for saving
variables for use by packages that are always restored on boot -- e.g. I was
thinking something like .Renviron but I think that's Rstudio only. I'm
concerned with workspace-type saves since I feel like that often results in a
ton of variables being saved.
Thanks!
