SOLVED. After some trials and errors, I got the code below:

perl << EOF
sub getrpath
{
use Win32::Registry;
my ($rkey);
my ($var);
my ($type);
my ($p) = 'SOFTWARE\R-core\R';
$HKEY_LOCAL_MACHINE->Open($p, $rkey);
$rkey->QueryValueEx("InstallPath", $type, $var);
VIM::DoCommand("let b:rinstallpath = '$var'");
}
EOF
