segfault with readDCF on R 3.1.2 on AIX 6.1 when using install.packages
Hi,
Note that one significant change to read.dcf() that happened since R
3.0.2 is the addition of support for arbitrary long lines (commit
63281), which never worked:
dcf <- paste(c("aa: ", rep(letters, length.out=10000)), collapse="")
writeLines(dcf, "test.dcf")
nchar(read.dcf("test.dcf"))
# aa

rsynd-2.5.1 / batch.c patch
Platform: Compaq OpenVMS Alpha 7.3
Compiler: Compaq C T6.5
The following patch is an update to a previous patch that I submitted.
The only change from the previous patch is that the const qualifier has
been added to write_batch_*() routines to improve compiler efficiency.
Because the gdiff -u was done against the distribution it includes the
previous patch.

Problem with Action:Originate with ASterisk Manager
Hi Asterisk-users,
I am working with Aterisk Manager API's.
I can login successfuly with the following.

read.table problem on Linux/Alpha (seg faults caused by isspace(R_EOF)) (PR#303)
Full_Name: Naoki Takebayashi
Version: 0.65.1
OS: Linux/Alpha
Submission from: (NULL) (129.79.224.171)
When I was reading a file with read.table("junk.data"), it seg-faulted.
I found out that it seg-faulted when the last line of data file didn't
have the newline char. For example, file like this:
23 3
31 2
24 1<EOF>
Here is a fix.

"Buff" memory grows
Hi.
I have shifted from redhat 7.1 to 7.2, and have several machines running
both versions now. I have noticed, that the memory usage patern is very
different on machines using ext2 and ext3 - the ones using ext2 usually use
5-10 MB of "buff" memory, but the ones with ext3 grow to 50MB on machines
with 128MB, and to 250MB with on machine with 512 MB. I have conducted a

rep for multiple categories
Hi,
I am R beginner and am trying to figure out how to generate a complete list of species for every point, visit, and year. The code below is close but does not give me a list of species for every point, visit, and year in my data set.
spplist<-unique(sumPtCt$Species)
spplength<-length(spplist)

[PATCH] cpu.c: initialize a variable
Some debugging tools don't like if a code uses unitialized variables.
The code in cpu.c uses the value of fxsr.buff[50], so it makes sense
to explicitely initialize it (because fxsave can fail to do it).

Problems with the Speex Jitter Buffer
Hi,
I am using the JitterBuffer. Since there is not so much documentation I
think I dont use it in a correct way. All the packets are recieved (I
control the sequence numbers) but the JitterBuffer often tells me he has
no packet. I am using it in the following way:
I am not sure if I use the ticks correctly but I think it can be set to
20(msec).

sprintf("%d", integer(0)) aborts
In R's sprintf() if any of the arguments has length 0
the function aborts. E.g.,
> sprintf("%d", integer(0))
Error in sprintf("%d", integer(0)) : zero-length argument
> sprintf(character(), integer(0))
Error in sprintf(character(), integer(0)) :

segfault with readDCF on R 3.1.2 on AIX 6.1 when using install.packages
Here's an update:
I checked the ChangeLog for R, and it seems like readDCF was changed
in 3.0.2. I went on a whim and copied src/main/dcf.c from R 2.15.3
over to 3.2.2, and R compiled fine and install.packages now work for
me.
This is probably not ideal, but it at least makes R usable on AIX for
me. Would definitely like to help figure out what's wrong with the
new dcf.c on AIX.

Problems with the Speex Jitter Buffer
Thanks for your reply Jean-Marc!
this was what I had before.
But I decided to restructure it since the thread that plays the sound is
a callback from the sound hardware, more or less an interrupt handler.
For me it seems more reasonable to waste some memory for to save the
decompressed Packet. While I write this I begin to think that it is
possible I decompress Packets that are never used
