Is this a bug in - ? No, it's a feature. The fact that x-5 works is arguably a bug (though probably not worth fixing). x[1] - 2 is equivalent (per section 3.4.4 of the language guide) to `*tmp*` - get(x, envir=parent.env(), inherits=TRUE) `*tmp*`[1] - 2 x - `*tmp*` and the get() fails when you try to do this from the command line. Since the point of superassignment is to assign in a lexical parent environment it makes no sense to do it directly at the command line. -thomas Thomas Lumley Assoc.

[R] problem in my code
Dear R-users I wrote a small program for assigning a membership Here is my script sample.size - 60 x - rnorm(sample.size, 0, 1) y - rnorm(sample.size, 0, 1) x.mean - mean(x) y.mean - mean(y) membership - numeric(sample.size) for (i in 1:sample.size) { if ((x[i] x.mean) (y[i] y.mean)) { membership[i] - 1 } else { if ((x[i] x.mean) (y[i] y.mean)) { membership[i] - 2 } else { if ((x[i] x.mean) (y[i] y.mean)) { membership[i] - 3 } else { membership[i] - 4 } } } } cbind(x,y,membership) There is an error message Error: object membership not found I can't figure it out. Any help or advice on improvement for this code will be appreciated. I konw this code is not well written at all.

Re: [R] problem in my code
Hi, How about replacing all - with -? That error occured in membership[i] - 1 this line and this code stopped before cbind(x,y,membership) this line. Hope this may help you. --- W.
