That may actually be the case for EVERY default plot, if I understand
correctly. The default S# plot is defined as
## Default S3 method:
plot(x, y = NULL, type = "p", xlim = NULL, ylim = NULL,
log = "", main = NULL, sub = NULL, xlab = NULL, ylab = NULL,
ann = par("ann"), axes = TRUE, frame.plot = axes,
panel.first = NULL, panel.last = NULL, asp = NA,
xgap.axis = NA, ygap.axis = NA,
...)
By putting in the comma, unless I am mistaken, you are effectively
saying the second element is NULL, which is how it's naturally
defined.
Thanks,
Avi
