axTicks does not do anything since that function simply computes
certain numbers and returns them.  It has no effect on the plot.  You want
to put xaxt = "n" as an arg to plot to suppress the axis and then:

	axis(1, at = c(0.1, 0.5, 1.0, 5.0, 10.0, 50.0, 100.0))

There are some examples in the example section of ?plot.zoo in
the zoo package.

You are trying to graph the log of 0 !

Also:

1. Replace your call to par with:

op <- par(...whatever...)

and then at the end

par(op)

to reset it.

2. You may wish to specify text.width = 0.2 in the call to legend (or
other number) to control the legend width.

3. Please read the last line of every message to r-help and please try to
reduce your problems in all cases to the smallest problem that illustrates
it rather than posting your original.

4. check out ?matplot
