I recommend that you calculate indicator values yourself.  If you
download them, you will be limited to parameter values provided by the
data provider.  You can calculate all the popular indicators with
functions in the TTR package.

I'm the author of TTR, and maintain quantmod, xts, and some other
packages.  I'm interested in what I can do to help make those packages
more accessible to users with sight impairments.  Please email me
directly, since that is off-topic for this list.

Best,
Josh
