(Various private e-mails exchanged. Again, thanks Dirk!)
Just in case anyone else is trying to do this, it turns out that if you can
persuade your end users to install the library to ~/R/library, then you can
say:
#!/usr/bin/r --vanilla
library(brainwaver, lib.loc='~/R/library')
although in my case, brainwaver depends on another library, which it now
can't find, so actually I have to load them in order:
#!/usr/bin/r --vanilla
library(waveslim, lib.loc='~/R/library')
library(brainwaver, lib.loc='~/R/library')
Alternatively,
#!/usr/bin/r --vanilla
.libPaths('~/R/library')
library(brainwaver)
works, although be careful, I've noticed that it seems to behave a bit
strangely on my debian setup.
e.g.
#!/usr/bin/r --vanilla
cat(.Library,'*****', .libPaths(),"\n")
.libPaths('~/R/library')
cat(.Library,'*****', .libPaths(),"\n")
gives output
/usr/lib/R/library
***** /usr/local/lib/R/site-library /usr/lib/R/site-library /usr/lib/R/library
/usr/lib/R/library ***** ~/R/library /usr/lib/R/library
that is, it seems to have removed /usr/local/lib/R/site-library
and /usr/lib/R/site-library as well as added ~/R/library
Cheers, John.
