'...' does not "eat" parameters, it passes them on.
Looking at the very top of the body we see this in the definition of the
internal `plotts` function:
cex = par("cex"), lty = par("lty"), lwd = par("lwd"),
axes = TRUE, frame.plot = axes, ann = par("ann"), cex.lab =
par("cex.lab"),
col.lab = par("col.lab"), font.lab = par("font.lab"),
cex.axis = par("cex.axis"), col.axis = par("col.axis"),
And at the end of the body we se the call to plotts (including the "dots")
So I would suggest using par-settings.
par(cex=0.5)
plot(y, type = 'b', pch = 16)
(Question seems more appropriate for r-help.)
