Hi all, Is there any way to keep numeric colnames as is? Any hint will be appreicated. Xin Zheng [[alternative HTML version deleted]]

Hi there, I got a data frame with more than 200k columns. How could I get median of each column fast? mapply is the fastest function I know for that, it's not yet satisfied though. It seems function "median" in R calculates median by "sort" and "mean". I am wondering if there is another function with better algorithm. Any hint? Thanks, Xin Zheng

Hi there, Suppose the cmd is "a<-3", I can parse the cmd sexp with R_ParseVector and eval it. My question is - is it possible to parse a cmd like "a <- ?", afterwards evaluation will give corresponding result depend on different argument? In other words, '?' is just a placeholder. Thanks.

Full_Name: Version: 2.9.0 OS: windows, linux Submission from: (NULL) (128.231.21.125) In NEWS, it says "median.default() was altered in 2.8.1 to use sum() rather than mean(), although it was still documented to use mean(). This caused problems for POSIXt objects, for which mean() but not sum() makes sense, so the change has been reverted." But it's not reverted yet.

Hi guys, I am trying to display Javascript code after an Ajax call. It is executing the JS code, but it''s also displaying it. It shows as: try { alert(...); } catch .. ... my controller code: render :update do |page| page.alert message_var end my Javascript code: new Ajax.Updater("div_id", my_controller_url, { asynchronous: true, evalScripts: true,

This problem is found in meego testing: http://bugs.meego.com/show_bug.cgi?id=6672 A file in btrfs is mmaped and the mmaped buffer is passed to pwrite to write to the same page of the same file. In btrfs_file_aio_write(), the pages is locked by prepare_pages(). So when btrfs_copy_from_user() is called, page fault happens and the same page needs to be locked again in filemap_fault(). The fix is to

Steven, I found where the difference is, it may be my fault: My changeset number + 1 = your changeset number. My 11160 is your 11159, and my 11161 is your 11160.

Hi, I have two questions re the Exception Notifier plugin (i.e. which you install via "ruby script/plugin install exception_notification") Q1 - In it''s current setup (where it uses /public/500.html) is it possible to remove the "Status: 500 Internal Server Error Content-Type: text/html" text which seems to mysteriously get place at the top of the page? Q2 -

Hi, I have read R's Writing Extensions manual and am still confused about how to use some of the routines there when I call from C. Specifically, I am writing a little test function which I will optimize using the nmmin function which underlies R's optim() with Nelder-Mead. I guess I wonder what library/header files I should be using. I was using R_ext/Applic.h and linking with libR but I

Hi, Suppose I have a multidimensional array: tmp <- array(1:8, c(2,2,2)) is there a function out there that, given a one-dimensional array index, will return the separate indices for each array dimension? for instance, tmp[8] is equivalent to tmp[2,2,2]. I'd like to derive the vector (2,2,2) from the index 8. thanks, Brad Buchsbaum

We have tested the latest xen on VT platform with Intel 915/E8500 chipset. Here is the test summary: Issues: - Cannot boot Four VMX at same time on IA32 host - Cannot boot Windows XP SP1/SP2 on IA32e host - Create IA32-PAE VMX on IA32e host will make VMX kernel panic - Create IA32 VMX on IA32e host will make VMX hang - Destroying VMX with 4G memory may make xend hang on IA-32e IA-32: -

This patch implements a new mechanism to buffer the MMIO_WRITE and PIO_WRITE packet in a queue, and then submit them to qemu-dm in batch. This could save a lot of domain switch time. We implement this as a generic one to do ioreq in batch. However, we only use it to batch the MMIO_WIRTE request for stdvga(0xA0000-0xC0000) in order to solve the win2k boot issue for hvm domain. Without this patch,

an obvious fix to PIC IO intercept. In PIC IO, address from send_pio_req is physical address already.

Attached are the patches to support super page with EPT. We only support 2M size. And shadow may still work fine with 4K pages. The patches can be split into 3 parts. Apply order is as attached. tool.diff To allocate 2M physical contiguous memory in guest except the first 2M and the last 2M. The first 2M covers special memory, and Xen use the last few pages in guest memory to do special

Sorry, maybe it's easy but I haven't found anything useful: how can I obtain a list C that contains all the members in the list B that are not in list A? This are lists of nanes, not numbers!

Keir, It''s a resending patch for the timeout mechanism to deal with the shared interrupt issue for vt-d enabled hvm guest. We modify the patch following your comments last time and make some other small fix: 1) We don''t touch the locking around the hvm_dpci_eoi(). 2) Remove the HZ from the TIME_OUT_PERIOD macro which may confuse others. 3) Add some
