Here's where this question comes from, may be this use case inspires
someone :-). I've a "big.int", that should behave like an i32. The
big.int routines are provided by a C runtime. To illustrate:
----------------------
; int func(int a, int b) { int c = a; return b; }
; using a regular int
define i32 @func1(i32 %a, i32 %b) {
%cp = alloca i32
store i32 %a, i32* %cp

a^b when a is large and b < 1 (64bit R on windows 7)
Hi,
I'm getting some strange behaviour when trying to use the power operator
(a^b) when a is large and b is less than one:
big <- .Machine$double.xmax
big
big^0.5
sqrt(big)
> big <- 1.797693134862315708384e+308
> big^0.5
[1] Inf
> sqrt(big)
[1] 1.340781e+154
I'm guessing that this behaviour is not expected, or am I missing
something about ^?
Cheers

Why is format(10000, big.mark = "\\,") not 10\,000?
Hi,
why does format(10000, big.mark = "\\,") not give me "10\,000"? How can I get this kind of "big.mark"?
Cheers,

kmeans.big.matrix
Hi,
I'm playing around with the 'bigmemory' package, and I have finally
managed to create some really big matrices. However, only now I
realize that there may not be functions made for what I want to do
with the matrices...
I would like to perform a cluster analysis based on a big.matrix.
Googling around I have found indications...

e2fsck message "inode is too big"
Hallo List,
after rebooting one of our systems one of the ext3 filesystems, that was
cleanly unmounted, fsck stopped the boot process due to critical errors in
that filesystem.
Running fsck -y manually returned, that one of the i-nodes is "too big" an
was truncated.
After this about three million i-nodes were orphaned an moved to
lost+found.

Aggregate to find majority level of a factor
I want to use the aggregate function to summarize data by a factor (my
field plots), but I want the summary to be the majority level of another
factor.
For example, given the dataframe:
Plot1 big
Plot1 big
Plot1 small
Plot2 big
Plot2 small
Plot2 small
Plot3 small
Plot3 small
Plot3 small
My desired result would be:
Plot1 big
Plot2 small
Plot3 small
I can't seem to find a scalar function that will give me the majority
level.
Thanks in advance,

different shares use parts of the same path - is this allowed?
hi everyone
something like this:
[big]
path = /data/big
writeable = no
[my.big]
path = /data/big/my
writeable = yes
[your.big]
path = /data/big/your
writeable = yes
is such a configuration healthy? What are possible negative
implications this may cause, if any?

many thanks,

processing of /vignettes and /inst/doc
...xternal
manuals and other files in /inst/doc will be installed.
This behaviour has been used to deal with the situation where a package has
two "vignettes", one that is easily processed and one that has a long
running time. This could be done by having
/vignettes/small.Rnw
/inst/doc/big.pdf
with obvious notation. Now, big.pdf is really produced by a Sweave
document, so what we really have is
/vignettes/small.Rnw
/inst/doc/big.pdf
/inst/doc/big.Rnw
This used to work, in the sense that the tarball produced by R CMD build
produced
/inst/doc/small.Rnw
/inst/doc/small.pdf...

RData size
...puzzling to me. Attached find 2 example
datasets in text file. Both are 100x5, so the sizes for both text file are the
same. However, when I read them into R, the sizes are much different:
tt<-as.matrix(read.table("tt.txt",header=T,row.names=1))
save(tt,file='tt.RData')
tt.big<-as.matrix(read.table("tt.big.txt",header=T,row.names=1))
save(tt.big,file='tt.big.RData')
"tt.RData" is 2KB while "tt.big.RData" is 5KB. This is not a big deal with the
example datasets, but my real datasets are much larger, the difference is 35MB
vs. 1M...

Hi,
With reference to the mail below, I have large datasets, coming from various
different sources, which I can read into filebacked big.matrix using library
bigmemory. I want to merge them all into one 'big.matrix' object. (Later, I
want to run regression using library 'biglm').
I am unsuccessfully trying to do this from quite some time now. Can you
please suggest some way? Am I missing some already avai...
