[R] plotting with an its object

[Laura Holt]

Dear R People:
I have an its object.  The original its is the Dow Jones Industrial average 
from March 23, 1990 to March 23, 2000.  I did the following;

dj1 = original series
dj2 <- log(dj1)
ddj2 <- diff(dj2)
Ok so far.
Now I would like to plot this series with a certain y limit:
min(ddj2)
[1] -0.07454905
max(ddj2)
[1] 0.04860535
plot(ddj2,ylim=c(-0.1,0.1))
Error in plot.default(x, y, xaxt = "n", xlab = xlab, axes = axes, frame.plot 
= frame.plot,  :
       formal argument "ylim" matched by multiple actual arguments

What is wrong, please?
I checked the following:
       formal argument "ylim" matched by multiple actual arguments
?plot.its
Error in help("plot.its") : No documentation for `plot.its' in specified 
packages and libraries:
 you could try `help.search("plot.its")'
its.plot
Error: Object "its.plot" not found
?its.plot
Error in help("its.plot") : No documentation for `its.plot' in specified 
packages and libraries:
 you could try `help.search("its.plot")'

but to no avail.
R Version 1.9.1 for Windows
Thanks in advance for any suggestions.
Sincerely,
Laura
