Interesting effect... 

I don't know what the real cause is, but evidently it is the axis
labels that are off (looking like what you get from applying deparse
to a vector/chron object), so a quick fix would be to set xlab and
ylab to sensible text strings. I.e.

plot(a, b, type='l', xlab="a", ylab="b)

Do you think you could cook up a small example (e.g. using simulated
data) exhibiting the same behaviour?
