Ah, I figured how to use z.test in R (over lunch ;). Yes, it does give the same 
results as Excel:
z.test(x,100,5,'greater')

Even with the mean on the other side 
y<-c(110,105,105,100)
z.test(y,100,5,'greater')

I'm now convinced that 'one-sided' is the correct description for what Excel 
does - not one- or two- tailed.
