[R] Getting error message using R: Please help (it's coursework due in on Friday)

[ethanhaas]

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.
