Require

It is easier to run a script if we know the packages will be installed if this additional step is necessary. 
Installation uses the RStudio mirror of CRAN.

Blind users do not have access to the graphical output from R
without printing the content of graphics windows to an embosser of
some kind. This is not as immediate as is required for efficient
access to statistical output.  The functions here are created so that
blind people can make even better use of R. This includes the text
descriptions of graphs, convenience functions to replace the
functionality offered in many GUI front ends, and experimental
functionality for optimising graphical content to prepare it for
embossing as tactile images.
