[R] Translation of R code required

[Sarah White]

I am using Windows XP, R version 2.4.

The code works until I get to the fourth line starting

model.effect

and I receive the following Error message.

Error in eval(expr, envir, enclos) : object "Centre" not found

When I say it works until the fourth line I mean I dont get an error 
message until then. It doesn't necessarily mean it has done what it 
should have done before then.

Thanks for the help.

Sarah
