Hi,
I've got something strange going on. I'm trying to compile a vignette using
Sweave("vignette.Rnw"), and in the first code chunk that illustrates an
example, I noticed from the output text I have inside the function, that it is
running it twice, because the sequence of message() statements is output on
screen twice, and takes twice as long to do.
e.g.
Processing sample 1
Processing sample 2
Processing sample 3
Processing sample 1
Processing sample 2
Processing sample 3
If I open up a new R session, and copy and paste the lines of code from the
.Rnw one by one, the function isn't called twice - only one complete set of
progress outputs show.
I tried using debug() to get more of an idea of what was happening. The
function is called enrichmentPlot, so I did debug(enrichmentPlot), then
Sweave("vignette.Rnw"). Execution pauses when it gets to the right code chunk,
then I type in "n" at the Browse[2]> prompt, but I don't get any output from
debug, like "debugging in:", but it runs for a while and I get all of the
messages from within my function, then execution pauses again. But just before
it pauses I get the debug output :
debugging in: enrichmentPlot(samples.list, 300)
debug: standardGeneric("enrichmentPlot")
Browse[2]>
Then I enter "n", and it runs the same code all over again.
... ... # Same progress outputs from inside my function.
exiting from: enrichmentPlot(samples.list, 300)
I have the current 2.13.0 version of R. I'm sure I've done something wrong, I
just can't figure out what. Thanks for any help.
