Hi Mat, glancing at what I believe to be your package sources [1]
You have non-R exposition in your \examples{...}. Examples are code --
you should be able to run them like any other code.
Moreover, they should be self-contained -- expecting the user to
create 'oildata' themselves won't work.
Why not use
oildata <- read.csv(system.file("extdata", "oildata.csv", package="olr"))
Inside the example instead?
You might also consider turning 'oildata' into a proper data object
exported by your package [2]

PS your text got mangled, it's quite hard to read your message -- I've
made a best effort to do so. Look how it renders [3]. Please turn on
'Plain text mode' for messages to this list to avoid this issue.
