matrix operations on grobs and grid units
Dear list,
As a minimal test of a more complex grid layout, I'm trying to find a
clean and efficient way to arrange text grobs in a rectangular layout.
The labels may be expressions, or text with a fontsize different of
the default, which means that the cell sizes should probably be
calculated using grobWidth() and grobHeight() as opposed to simpler
stringWidth() and stringHeight().

Fetching Binary data from SQL Server
I am trying to write a customized app using C that would fetch voice file from SQL Server 2000 using ODBC and FREETDS.
Currently I am only able to fetch first 63 KB chunk from the DB, and not able to fetch the rest of the file, below is the code that i am using to do so,
fd = open(fullpath, O_RDWR | O_CREAT | O_TRUNC, 0770);

Column(row)wise minimum and maximum
Hi,
Currently, the "base" has colSums, colMeans. It seems that it would be useful to extend this to also include colMin, colMax (of course, rowMin and rowMax, as well) in order to facilitate faster computations for large vectors (compared to using apply). Has this been considered before? Please forgive me if this has already been discussed before.
Thanks,
Ravi

.Call and data frames
Hello,
I'm trying to fetch a data frame through the C API,
and have no problem doing this when all columns
are numbers, but when there is a column of
strings I have a problem. On the C-side the
function looks like:
SEXP myfunc(SEXP df),
and it is called with a dataframe from
the R side with:
.Call("myfunc", somedataframe)
On the C side (actually C++ side) I use code
like this:

How to use `[` without evaluating the arguments.
Hello R-devel,
I am currently attempting to implement an API similar to data.table wherein single bracket subsetting can accept an unquoted expression to be evaluated in the context of my object.
A simple example from the data.table package looks like this:
DT <- data.table(col1 = c('a', 'b', 'c'), col2 = c('x', 'y', 'z'))

[PATCH] vhost/net: length miscalculation
commit 8b38694a2dc8b18374310df50174f1e4376d6824
vhost/net: virtio 1.0 byte swap
had this chunk:
- heads[headcount - 1].len += datalen;
+ heads[headcount - 1].len = cpu_to_vhost32(vq, len - datalen);
This adds datalen with the wrong sign, causing guest panics.

Problems with two B channels
Hello all,
I'm trying to get CAPI to work with two B channels (AVM B1 PCMCIA)
on a P4 2GHz (linux kernel 2.4.21) system. All are ok with just one
B channel. But when I open a second B chan, the sound is choppy,
with too long gaps, and the CPU load is too high (~50%).
On the Asterisk's console I get these messages:

[PATCH net] vhost_net: do not report a used len larger than receive buffer size
Currently, even if the packet were truncated by lower socket, we still
report the packet size as the used len which may confuse guest
driver. Fixes this by returning the size of guest receive buffer instead.

Memory problems...leaky?
Hi list folks,
I have been trying to figure out how I can run the script that I have
included below. I have 1.2 gigs of memory on the computer, but this is
not enough, given the size of the input datasets. The input matrix
('input') is a little under 2400 x 2900 cells, and is about 60 megs when
stored on hard drive...what is R doing, that this (small) size of file
takes up so much
