Lazy loading is still not accepted and the library can be compiled only

Thanks for all the good points. I raised the question not because I doubt the R
system, but I think it is a common point for all the open code software.
Personally I really appreciate the open source software, and nowadays,
there are more and more open source, especially in the academic area.

Or maybe just
unique(t(apply(h,1,sort)))

There may be more efficient ways, but
unique(t(apply(h, 1, sort)))
does what I think you want.

Dear list,
I would like to extract from a matrix all those rows, that are unique.
By unique, I don't mean the unique that is accomplished by the function
unique(), though...
Consider the following example:

[2,]14
[3,]41
Now unique(h) returns exact

You can even use
newdat <- subset(a, V3 == "O")
because of the way that subset evaluates the "subset" expression.
