What does the warning mean?
In dev.off() : increasing the PDF version to 1.3
It means you have an obsolete version of R, and failed to follow the
posting guide in telling us what it is. ?pdf should explain the message
to you in your version of R. E.g. 2.6.0 has
version: a string describing the PDF version that will be required to
view the output. This is a minimum, and will be increased
(with a warning) if necessary.
The 'version' argument declares the version of PDF that gets
produced. The version must be at least 1.4 for semi-transparent
output to be understood, and at least 1.3 if CID fonts are to be
used: if these features are used the version number will be
increased (with a warning). Specifying a low version number (as
the default) is useful if you want to produce PDF output that can
be viewed on older or non-Adobe PDF viewers. (PDF 1.4 requires
Acrobat 5 or later.)
The default value is "1.4" these days.
