HOW TO USE tuneR ON MACS WHEN YOU HAVE LIMITED PRIVILEGES
Don Byrd, rev. 7 Sep. 2007


Security-related restrictions on Macintosh computers can make it difficult
to use tuneR, the R package we use for handling audio files. Here's how to do it.

(Note: This document was originally written to explain how to use tuneR
on the Macs in the Music Library computer lab, M373; but tuneR is now
pre-installed on those computers, so this procedure should never be
needed there. However, if you want to use it on Macs in other STCs, or
other computers that you have only limited privileges on, it may still
be necessary.)


1. Launch R.

1. Type install.packages() (or use the menu command equivalent)

2. In the Install dialog, apparently the defaults sometimes work -- I don't
know why. If they don't, choose:

	* Other Repository
	* In Other Location
	* Get List

   Then select tuneR from the list and click Install Selected. In the
   dialog, choose Documents.

3. To actually make tuneR usable, if the default install worked, use the usual
simple "library" command:

    library(tuneR)
    
Otherwise, you need a more elaborate form:

    library(tuneR, lib.loc = "Documents")

That should be all you need to do.
