The sshc(10,100) was just some numbers I plucked out of nowhere. Your
definition:
sshc<-function(rc, nc=500, d=.5, method=3, alpha=0.05, power=0.8,
+ tol=0.01, tol1=.0001, tol2=.005, cc=c(.1,2), l.span=.5)
actually probably only needs the first value, the other parameters
will take the defaults. sshc(10) should minimally run.
[[pedantic note
I say probably because R code can look like this:
foo = function(x){
if(missing(x)){x = 99}
...
}
which is the same as foo = function(x=99){...} - so just because
there's no default in the function definition it doesn't mean you have
to supply it.

Not sure why you have to click 'stop' - it might be that there's a
couple of 'while' loops in there which might not be terminating.
There's what looks like some debugging calls to 'cat' commented out -
if you uncomment them you'll see what's going on, but you might not
see them as they happen in Windows since I dont think the output isn't
normally flushed immediately. There's probably an option you can set
or a flush function you can call....
