[Orgmode] selective export

[Graham Smith]

Using babel I have the data used for the analysis (in R) under a top
level heading just called data. I want to keep this in the org file
but not in the compiled pdf.

I have had a look at the selective export in the manual, but could do
with a bit more step by step instructions on how to exclude this bit
of the outline.

Could someone give me a bit of hand holding on how to do this.

Many thanks,

Graha,
