txtMergeLines: A merges lines while preserving the line break for html/LaTeX
Description
This function helps you to do a multiline
table header in both html and in LaTeX. In
html this isn't that tricky, you just use
the <br /> command but in LaTeX I often find
myself writing vbox/hbox stuff and therefore
I've created this simple helper function
Usage
txtMergeLines(..., html = 5)
Arguments
...
The lines that you want to be joined
html
If HTML compatible output should be used. If FALSE
it outputs LaTeX formatting. Note if you set this to 5
then the html5 version of br will be used: <br>
otherwise it uses the <br /> that is compatible
with the xhtml-formatting.
