R help - Dec 2007 - Getting error message using R: Please help (it's coursework due in on Friday)

I've been trying for the past 3 weeks to use R (much better than Matlab but
I
am very bad with computers so I am very new to all of this) and know how to
input the data (hey, it's a start!) but every time I type in the following:

dcm <- decompose(information)

I get the following error message:

Error in decompose(information) : time series has no or less than 3 periods

Could you please aid me so that I can progress to the next step. What I am
in fact trying to do at the moment is plot a graph of the information so I
had assumed it would be:

dcm <- decompose(information)
Plot(dcm$trend)

but obviously it does not appear to be the case.

By the way the code I have right now in case it helps is:

information <- scan("everything.txt")
timeseries <- ts(information, frequency = 11, start = c(1970, 1994))
using <- window(timeseries, end = c(1990, 11))
dcm <- decompose(information)
Plot(dcm$trend)


Thank you very much in advance, I really appreciate the help.

Er, are you sure it is "information" that you want to decompose()? (If
so, what are the computations of "timeseries" and "using"
supposed to be
good for?)
