unique possible bug
Hi,
I am trying to read in a rather large list of transactions using the
arules library. It seems in the coerce method into the dgCmatrix, it
somewhere calls unique. Unique.c throws an error when n > 536870912;
however, when 4*n was modified to 2*n in 2004, the overflow protection
should have changed from 2^29 to 2^30, right? If so, how would I
change it in my copy? Do I have to recompile

Vector size limit for table() in R-2.15.1
Hi,
First, thanks in advance. Some useful info:

arch x86_64
os linux-gnu
system x86_64, linux-gnu
version.string R version 2.15.1 (2012-06-22)
I'm trying to use the table() function on a 2 column matrix that has 711
million rows (see below). However, it freezes. If I subset the matrix to be
less than or equal

Does rJava offer a way to instruct the JVM to perform a garbage collection?

correlation structure in lme without random effect
I was hoping to fit along the lines of
g<-gl(20,5)
y<-runif(100)
fit<-lme(fixed=y~g,correlation=corAR1(0,~1|g))
But I get the error "Incompatible formulas for groups in "random" and
"correlation""
Any help would be greatly appreciated.

OpenBLAS in everyday R?
I didn't do the compile; is there a way to check whether that was used?
If not, I'll inquire with our sysadmin and report back.
In any case, my suggestion was motivated by the fact that some parts of
R use OpenMP while others do not, in the hope that the former could have
their OpenBLAS omelet without breaking the OpenMP eggs, so to speak.

Error in close.connection(p) : ignoring SIGPIPE signal
Andreas,
How right you are! Still, I find it curious that in the context of the
while(TRUE) loop, I am allowed to do this 653 times, with failure on the
654th attempt. Perhaps there is something asynchronous going on? If I
eliminate the looping, it does indeed fail (as expected) on the first
attempt to close the pipe.
Regards
Ben

rpois(9, 1e10)
So imagine rpois is changed, such that the storage mode of its return
value is sometimes integer and sometimes numeric. Then imagine the case
where lambda is itself a realization of a random variable. Do we really
want the storage mode to inherit that randomness?

[LLVMdev] ADT/Hashing.h on 32-bit platforms
Hi,
Currently the hashing implementation in ADT/Hashing.h produces hash
values on 32-bit platforms that differ from the lower 32-bits of the
hash values produced on 64-bit platforms. It seems the only reason for
this difference is that the uint64_t integer seed is truncated to
size_t. Since the usage of uint64_t and size_t as types for seed values
in the implementation is somewhat

The docs a re a bit weird on "Directory hashing"
In squid we use a double layer of hashed directories on the FS to allow
storage of millions of files.
I was reading the "Directory hashing" section but never understood it..
since it's written.. in a way I could not understand.
I am using this line:
mail_location = maildir:/home/vmail/%d/%n/Maildir/
and I want to migrate to a hash based directory scheme.

future update to loess
Background: I'm a student of Prof. Cleveland at Purdue University.
Eventually, we'd like to release a new version of the loess routine in R.
For starters, this implementation would have support for local polynomial
degree 3, better control over the number of cells in the KD tree, and
perhaps a better solution in higher predictor dimension.
I see that Prof. Ripley was responsible for

Error in close.connection(p) : ignoring SIGPIPE signal
Not sure if this is a bug, so posting here first. If I run:
?? cnt <- 0L
?? while (TRUE) {

? ? ?? p <- pipe("echo /dev/stdin > /dev/null", open = "w")
? ? ?? writeLines("foobar", p)
? ? ?? tryCatch(close(p), error = function(e) { print(cnt); stop(e)})
?? }
then once cnt gets to around 650, it fails with:

[LLVMdev] Q: clang, obj-c: Hashing selectors to SEL's.
I'm trying to understand the method dispatch in objc_MsgSend.
At some point during compilation, ascii selectors are hashed
into integer SEL's. Is this hash somehow guaranteed to be unique?
If so, how? If not, how are collisions handled? Is this hashing
done during the link phase?
Any insights/pointers to the code/documentation related to this
hashing would be greatly appreciated.

"too large for hashing"
Hello,
I'm doing some analysis on a rather large data set. In this case,
some simple commands are failing. For example, this one:
> x$eventtype <- factor(x$eventtype)
Error in unique.default(x) : length 1093574297 is too large for hashing
...I think this is a bug, because "hashing" should not be required for the
"factor" function. Am I right? The whole column
