Dear list. It is a known issue that accessing slots of S4 objects and in particular accessing .Data slots is slow in R. However, what surprises me are two things demonstrated in the code below (runnable with 'inline', my times are in the comments): - copying data out of a large 3x1e7 .Data slot into a matrix can be easily made 3-4 times faster than accessing a .Data slot which I believe

With PUBLISH_USED_IDX, guest tells us which used entries it has consumed. This can be used to reduce the number of interrupts: after we write a used entry, if the guest has not yet consumed the previous entry, or if the guest has already consumed the new entry, we do not need to interrupt. This imporves bandwidth by 30% under some workflows. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> --- Rusty, Dave, this patch depends on the patch "virtio: put last seen used index into ring itself" which is currently destined at Rusty's tree.

Hi, I am Tejas Nikumbh, an undergrad at Indian Institute of Technology Bombay. I will be participating in GSoC this year. [GSoC 2013]. In order to imporve my chances for getting selected this year, I would like to start contributing early on to Open Source development via xapian.

Dear List: I am encountering an error that I can't resolve. I'm looping through rows of a dataframe to generate individual tex files using Sweave. At random points along the way, I encounter the following error Error in file() : cannot find unused tempfile name At which point Sweave halts. There isn't a logical pattern that I can identify in terms of why the program stops at

...file from this process: figure_10.png figure_11.png figure_12.png ... figure_1.png figure_20.png ... So I would like to convert integers to something like 01 if upper limit for this conert is 10 or 001 for 100. I wrote a simple function (see below), but I do not know how this limit stuff can be imporved to work really well with default. Any suggestions? int2char <- function(x, limit = max(x)) { # Description: # Converts integer to character such that numbers bellow limit get 0 in # front # Gregor GORJANC, 2005-01-05 # Arguments: # x: vector of numbers #...
