Plots using POSIX
Is there a reason that the bottom axis changes color when POSIX data is used
in plot function?
For example:
> timedata <- c("2/3/2003","3/4/2003","5/4/2003")
> timedata2 <- strptime(timedata,format="%m/%d/%Y")
> numdata <- c(2,3,4)
> plot(as.POSIXct(timedata2),numdata,col="red",type="o")
As compared to:
> numdata2 <- c(3,4,5)

isdst warning when rounding a range of time data: fix or suppress?
Hi, I'm working with timeseries data. The values are every 5 seconds and each series can last up to 4-5 days.
To generate the x-axis labels, I'm doing the following:
=========================
# Variable for displaying hours on the x-axis
rtime <<- as.POSIXct(round(range(timedata), "hours"))
# Variable for displaying days on the x-axis
stime <<- as.POSIXct(round(range(timedata), "days"))
# Plot the hours on the x-axis
axis.POSIXct(1, at=seq(rtime[1], rtime[2], by="hour"), format="%H", cex.axis=.6, lwd=0, lwd.ticks=1, hadj=0.2,...

Introduction and patch
Hi,
I'm one of the people working on the Rockbox project
(http://www.rockbox.org) which is an open source alternative firmware
for a range Digital Audio Players. Recently we integrated support for
the Speex codec using libspeex and seems to work well. If you could add
Rockbox to your list of software that supports Speex, that'd be great.
So that's the introduction done. Now for

[LLVMdev] Issue with GetElementPtrInst in Instruction Combining pass
...quot;, "without instruction combining" is:
%coupling = getelementptr inbounds %struct._FRAME_DATA* %2, i32 0, i32 5, !dbg !575

Introduction and patch
Hi Dan,
Thanks for the patch, I'll apply it to svn. One question, why do you
need this:
+void kiss_fftri2(kiss_fftr_cfg cfg,const kiss_fft_scalar
*freqdata,kiss_fft_scalar *timedata);
+
Cheers,
Jean-Marc

...fset in FRAME_DATA i.e. the 6th element, i.e. coupling member variable.

2. with instruction combining

i.e. 1060 offset.
Still the location references by "without instruction combining" is 5 less from with instruction combining.
Earlier when I was using llvm2.9, instruction combining does not give me any problem. And similar code is generated as with llvm 3.0 instruction com...

ggplot equivalent of par(xaxt)
I am playing around learning ggplot and cannot see how to suppress the x or y axis values ( equivalent of xaxt in basic graphics)
It must be obvious but I'm not seeing it.

Hi Pankaj, your best bet is to send the entire bitcode before and after
instcombine runs.
Ciao, Duncan.
