R help - Jul 2015 - Problem accessing xslx on CRAN mirrir

I am very new to the use of R and trying to install it in order to use a package
called mh1823 for determining Probability of Detection stats for Non-Destructive
Evaluation.  I have hit an immediate problem installing the xlsx package and get
the following messages:

Warning: unable to access index for repository
http://star-www.st-andrews.ac.uk/cran/src/contrib
Warning: unable to access index for repository
http://www.stats.ox.ac.uk/pub/RWin/src/contrib
Error in install.packages(NULL, .libPaths()[1L], dependencies = NA, type = type)
:
  no packages were specified
In addition: Warning message:
In open.connection(con, "r") : cannot open: HTTP status was '0
(nil)'

I do not seem to be able to get past this issue, though am able to load the
mh1823 POD package successfully from local zip file

Regards,

Tom

It looks as though R couldn't make any connection.  Perhaps you are
using a proxy?  It looks as though you are on Windows; if so, you could
try running

setInternet2(TRUE)

before the install; that will use the proxy settings for Internet Explorer.
