# Introduction
See the Introduction pdf for the various examples and the relation of this example to the others.  

This example is the nearly the same as the previous example. The difference is that the parameter \mytextit{altplot} is now set to `r F` and  that the bibiography is now in an external file. The latter is convenient when you often reference the same items. The bibliography has to be specified in the yaml-header and is fully handled by Pandoc and not by the \LaTeX \ processor. Therefore the Pandoc way of referring has to be used and not the \BSLASH{cite} method.

# Load data and create plot object
Before plotting the iris data set (in `r ref_tab('r1a',F)`) we list the first `r numlist` (because we set variable \mytextit{numlist} to `r numlist` in a chunck we do not present to the reader) observations in the data set in  `r ref_tab('lbltab1',T)`.  
As an example of a reference we use [@myrefa]. You can also include a reference in an inline footnote as demonstrated here^[This footnote references [@myrefb] and [@article].].   
NB. using the \LaTeX \ \mytextbf{\BSLASH{footnote}}-command does not give the correct layout.
