Dear all

I am a newbie to R and I would appreciate it very much if someone can
give me some advice on this.

Please note that I am not a programmer so some of the questions might
sound really stupid.


I would like to compute McDonald's omega calculation using R, I'm
aware I can use the omega function in the psych package.

But I'm really not sure how to do it.


I have read these two articles that explain about omega-


http://personality-project.org/r/html/omega.html and
http://personality-project.org/r/r.omega.html


But I'm still not sure how to do it.


Can someone correct me what I have gone wrong.


I'm following the instruction from this site and I have downloaded the
psych package- http://personality-project.org/r/


*1. Load and read the data*


datafilename <- file.choose()     # use the OS to find the file

person.data  <- read.table(datafilename,header=TRUE)  #read the data file



*2. Use the code examples from http://personality-project.org/r/r.omega.html*


Copy and paste the whole code from this website in the R console



I know I must have understood Step 2 incorrectly, but I am really not
sure what to do with the omega function.


Can someone give me more specific help on this please.


Thanks.
