It might become possible in the future. There are a couple of
complications that get in the way: You cannot use a shell script
(which /usr/bin/R is) in a #! line, and even if you could, R would be
called with the script as an argument, and it currently doesn't handle
What you *can* do is stuff like
[pd at blueberry pd]$ cat > xxx.RR
R --vanilla --quiet << __END__
x <- c(1:10)
[pd at blueberry pd]$ chmod +x xxx.RR
[pd at blueberry pd]$ ./xxx.RR
> x <- c(1:10)
