As pointed out by Brian Ripley on R-devel, co.intervals does xr <- x[r + ii]
with a fractional r, leading to intervals that don't match the ones returned by
S-PLUS when overlap=0 or 0.5. For example,

x<-1:10
z<-co.intervals(x,overlap=0) 

As I had already peaked at co.intervals in S-PLUS, I probably shouldn't be the
one to contribute a fix.
