There isn't a completely general way to do this, because there might
not *be* a directory
source("http://bioconductor.org/biocLite.R";)
source(textConnection("print('Hello, world.')"))
source("")
etc
However, source() has a chdir=TRUE option that sets the current
working directory to the directory of the file, if it is a file and
has a directory, and then getwd() will return that directory.
