Sorry, but we do not have the R software installed, and do not know how
to use it to read netCDF files.  We develop, maintain, and support the
netCDF library software, but other software packages, such as the R
statistical software, must be supported by their developers.  According to

  http://www.r-project.org/

there are two netCDF packages for R, one named ncdf and the other named
RNetCDF.  Unfortunately, I could not locate an email for support for either
of these packages.
