Erez, I think the API is very explicit about this, NULL is not an accepted input for any function taking SEXP by design. The special case of try*Eval() return values can be taken as a case where the resulting object is not actually SEXP but rather a special type which can be NULL (=failure) or SEXP. It may be even perhaps useful to declare it as a separate type to make this clearer, but I

Thank you Ivan, At this point, without it being documented explicitly, I tend to lean on the safe side. If the non-null assumption is ever incorrect, on debug and safe builds unwrapping is an assert that will guarantee to crash R. While the source code has plenty of NULL checks, also for some SEXP, it's hard to tell just from grepping if any are related to the public API or not. Secondly

Hi I need an advise if any one can help me. i have mass of data in 2 array A and B: A = 0 1 0 0 1 1 0 0 B = 0 0 0 1 0 1 1 1 and i have 3 rules to merge them into 3rd array C: if A[i] + B[i] == 0 then C[i]=0 if A[i] + B[i] == 1 then C[i]=1 if A[i] + B[i] == 2 then C[i]=2 it looks easy but with the regular way (loop) with large data it takes days (i test it). If any one can advise me what to do

Hello Speex. We are a small Canadian company currently researching the possibility of using Speex for an iPhone application. We wonder if Speex can be used to develop paid applications and if you require any fees or other payments if it used commercially Thank you. -- Erez T Yanuv Barzilay Digital Media | Interactive Design Graduate Student Center for Digital Media 577 Great Northern Way

Hi all, I installed Xen 3.4.0 on RH5.3 from the source, It is working fine (Dom0), but when i tried to create new guest (hvm) by the virt-install i got the next message: Wed, 23 Sep 2009 12:02:15 ERROR virConnectOpen() failed Traceback (most recent call last): File "/usr/sbin/virt-install", line 560, in ? main() File "/usr/sbin/virt-install", line 348, in main

Hi Peter and Group, First, thanks for great boot system. My goal is to create a boot process that is clean from any text message and shows simple graphics at startup. That graphic image will last until the X server is starting (with the same background, might be with different resolution). My reason is, that many end users prefer graphics on simple cryptic text messages. Messages will be

First I wanted to thank both Marc Schwartz Greg Snow and for their reply. Then I needed to add a level of complexity to the problem. I would be able to create the biggest possible matrix. In other way does it exist a method to ask smthing like the following : max number of rows for a matrix if column=x?

Hi, we're working on a stackable versioning file system for 2.4.x. Versioning can easily create lots of files for a file that gets modified frequently, and our current design puts all versions of a file in the same directory as the main file. We are therefore evaluating how stable and efficient different combinations of file systems would be in this scenario. We've run our versionfs on

This is a patch which Daniel Erez wrote originally. I have modified it only to fix a small bug in the debug() statement, and Ilanit kindly tested it here: https://bugzilla.redhat.com/show_bug.cgi?id=1680361#c38 Rich.

This increases the inactivity timeout for transfers from the default (60 seconds) to 1 hour, so that we should never hit it for ordinary transfers. Note this requires oVirt >= 4.3.0 although the same change was backported to the 4.2 branch in later releases. The corresponding oVirt fix was in https://bugzilla.redhat.com/1563278 I also replaced the deprecated ‘image’ parameter with ‘disk’.

That definitely looks like a bug, but not one that anyone will be eager to fix. It's very old code that tried to be clever, and that's the hardest kind of code to fix. Remember Kernighan's Law: "Everyone knows that debugging is twice as hard as writing a program in the first place. So if you?re as clever as you can be when you write it, how will you ever debug it?"

Hi, I tried to attach passrough io device to domU, the command (ended successfully in dom0), but when I entered the domU and typed the "lspci" command I didn''t see the new device, although the dom0 removed it from the "pci-list-assignable-devices". When I tried to detach it from the domU, the detach command returned with timeout error. What did I miss? perhaps I

At least I cannot find any mention of plot.first in the R source code. In this example,

Hello, I'm working on bindings for the API (for zig), and was wondering if the R's C API guarantees it won't return null pointers? The only reference I found in the "Writing R Extensions" manual where this not the case is `R_tryEval` and `R_tryEvalSilent`. Otherwise it's unclear. The reason I care about this is syntax. Because I don't know whether SEXPs are NULL or
