I am fully unfamiliar with some of the choices you may have, indeed I was asking earlier for some
names of scripting facilities, but I wrote a build script for my latex source code largely to
work with bibliographic entries that I found while composing.
For a recurring report however where generation time is not a big issue personally I would probably
write a bash script- you can get cygwin for example on Windows- and add
comments to your latex source or come up with a syntax for things that get modified each time. This
allows you to integrate R and anything else you may need with a very familiar command
Here is a simple example of a latex code generator for checking a bib adapted from the
below URL.This same approach works for html , c++ etc easily. You define the file names
in the bash script, use them to generate R script and latex and then you can keep track
of everything without a lot of language specific stuff. It is easily adaptable to many settings,
I have used R on servers to respond to queries for example, and the code gives you nice
references for later use.

Subject: [texhax] include a pdf graphics file whose name includes a varying date
I am using R and Sweave and MikTeX on Windows 7. I use this workflow
to generate a recurring report quarterly. Same report, just new data.
The R code generates a graph, saving it as a pdf file, the filename
including the date. Each time I run the report, I want to include the
most current graph. How would I do that?
Example code (just excerpts, does not actually compile, but I think it
will convey my intent):
<<timeseriesplot, results=hide, echo=FALSE>>=
# make the major graph
pdf(file=paste("NaloxoneUseEMS-timeseriesplot-", Sys.Date(), ".pdf",
sep=""), height=8, width=12)
## bunch of R code in here to create a graph
The later in the file, I have:
here is the problem
How do I make this
part of the figure filename
increment to match SysDate()
from R in the code chunk above?
I understand I could just include the code-generating chunk inside a
Sweave environment with fig=TRUE, but I have some reasons for
preferring to save the graph as a pdf file and use it later.
