[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
