R help - Oct 2004 - x is not a open/high/low/close time series

I am trying to create a high low close style chart but I keep getting the 
following error statement; "x is not a open/high/low/close time 
series".  I've used the function is.ts and R responds TRUE but the 
ohlcPlot  function gives the above error statement. I'm actually planning 
to plot some odds ratios with their confidence intervals and the 
hi-low-close chart should do the job if I can just figure out what the 
ohlcPlot  function is expecting the time series data to look like.
Thanks for the help

If you do 'example(plotOHLC)', an object x is created, and a subsequent
'class(x)' tells you that it is of class 'mts' -- a multiple
timeseries
object.

Similar code and functionality using another data type is in the its package
on CRAN. You may find that easier to use. Depending on your R skills, you
can also factor out the OHLC plotting code and apply to data.frames or other
data containers.

Using is.mts(x) and colnames(x) check that these hold:

- the object is an "mts"
- the names of the first, second, third and fourth columns are
  "Open", "High", "Low" and "Close",
respectively
