no problem at all

not a QGIS problem, installing R under Windows and having it available
system wide is cumbersome. Is easier under Linux.

No, any 2.9 < R < 2.12 should be ok

You can use also R >= 2.12, you'll need a workaround

from 
http://www.qgis.org/wiki/HomeRange_plugin

"R >=2.12: From this version on, the R.dll location has changed, so it
isn't found automagically by rpy2. It raises a Unable to locate R.dll
error. You can fix that by editing or creating the RHOME variable,
pointing to the correct location. See the instructions above, and the
thread on the Animove mailing list"

translated:

install R

put the path to R binaries into the "Path" windows environment variable

install the necessary R libraries -> the plugin itself has a tool to
install the R libraries it needs, but I would advice you to install them
with the  R console

if you have Vista or Seven you will have then to copy the entire folder
that contains the R libraries into another folder, otherwise the plugin
will not work (I believe you can blame Windows for this)

from

C:\Users\your_username\Documents\R\win-library\2.12 

to

C:\Users\your_username\R\win-library\2.12

you see clearly how to set it in the screencast I linked in my previous
e-mail.

can you add manually the output to QGIS?
