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

Hey there - This morning I ran the yum updater through Webmin as I do every month or so - after about two hours I realized that I still had the same updating screen going - and no response. Seemed strange. Simple attempts to kill it didn't work so I sent a command to reboot the system - that seemed to work, till I turned on the monitor directly connected to the server - I saw this

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 # li...

hi, rgev function gives me random deviates and I have a data set which I am fitting to an EVD,IS there a way I can plot both observed and ideal evd on the same plot thankyou Rangesh

Hello guys.As discussed on IRC,I have sent a pull request for a test for testing TradWeight with an Rset.
