When I try to use the TSA::prewhiten function from within a Sweave (or
pgfSweave, the bug triggers either way it seems) code chunk inside a LyX
document, I get this error:

20:35:49.451:
20:35:49.452: Common reasons for failure include:
20:35:49.453: * The string contains a character which is special to LaTeX
unless
20:35:49.454: escaped properly, such as % or $.
20:35:49.455: * The string makes use of LaTeX commands provided by a package
and
20:35:49.464: the tikzDevice was not told to load the package.
20:35:49.466:
20:35:49.468: The contents of the LaTeX log of the aborted run have been
printed
above,
20:35:49.471: it may contain additional details as to why the metric
calculation
failed.
