A customer has a zpool where their spectral analysis applications create a ton (millions?) of very small files that are typically 1858 bytes in length. They''re using ZFS because UFS consistently runs out of inodes. I''m assuming that ZFS aggregates these little files into recordsize (128K?) blobs for writes. This seems to go reasonably well amazingly enough. Reads are a

Hi Xen folks! I''ve faced with one strange thing in ARM version of Xen: when I use xc_map_foreign_bulk() to map some memory from domU to dom0, after unmap() for previous returned address - memory is not freed at all. Let''s look at call stack: xc_map_foreign() -> linux_privcmd_map_foreign_bulk() -> { addr = mmap(fd); ioctl(fd, IOCTL_PRIVCMD_MMAPBATCH_V2 );

Hi all, I am having a little problem with S4 group generics (apologies if I get some terminology wrong below). I'm finding I can set methods for some group generic functions, but not others: > setClass("foo", representation(data="numeric")) > x <- new("foo", data=1:10) ## Setting "Ops" works just as expected: > setMethod("Ops",

I would like to output the following information when running a spec (_also_ on success): - the description text - the expected value - the actual value After looking through the documentation I thought custom formatters might be the way to go, but unfortunately it does not look like all variables are accessible from there? I need this for an academic report where all testing needs to be

The proposal is trying to garbage collect symbols that are not referenced during the link step. In addition this proposal can be extended to keep frequently called functions/data closer

I've not been following this thread at all. However, skimming the original post, I fail to find a nice summary of what problem is trying to be solved. By reading the rest of the thread I divine that the goal is faster links and better dead code stripping? Making that clearer would help. Naming your sections something other than "safe" (which has *very* different connotations) would

Hi, Infinite recursion in S3 methods seem to crash R on Windows 2000 (R terminating with the ("Rgui.exe has generated errors...") message, rather than throwing an error. This happens with both Rgui and Rterm. The following toy example triggers this: myf <- function(x, ...) UseMethod("myf") myf.default <- function(x, ...) myf(x) myf(1) ...R crashes... Which I

I'm working on a small server written in Go to add short-lived user certificates to the forwarded agents of authorized users. https://github.com/rorycl/sshagentca This seems to work quite well for accessing sshd servers with the appropriately configured "TrustedUserCAKeys" directive. I have been in a debate about how similarly adding host certificates to forwarded agents could

When I was preparing Xen''s netback driver for upstream one of the things I removed was the zero-copy guest transmit (i.e. netback receive) support. In this mode guest data pages ("foreign pages") were mapped into the backend domain (using Xen grant-table functionality) and placed into the skb''s paged frag list (skb_shinfo(skb)->frags, I hope I am using the right

First it asks for vDPA driver for virtio devices (VIRTIO_VDPA) support. If you say 'n', it then asks *again* for VDPA drivers (VDPA_MENU). And then when you say 'n' to *that* it asks you for

I have a dataset of the form Year tosk.fai tosk.isd tosk.gr ....... tosk.total hysa.fai hysa.isd ... and so on. I want to sum all the columns using the first four letters in the columns label(e.g. 'tosk', 'hysa' etc.). How can you do that? Also, the sums should be without the '.total'column (e.g. 'tosk.total') as this serves as a check that

Hi there, I am working on a project which needs the value of the interaction area under two distributions( eatimated by kernel density estimators). For example: x<-rnorm(100,0,1) y<-rnorm(100,0.2,1) density(x) # This produces the summary of dependent variable and independent variable. How can I get the individual values of variables and reform a curve to calculate the area under

Hi R! I am reading in a text file which has one column of alpha data and 5 columns of numeric data. There is a header row. I would like the alpha data column to just be character rather than factor. Is there a way to do this, please? I'm thinking that it might be I() but can't figure out exactly how. Thanks, Laura mailto: lauraholt_983 at hotmail.com R 2.0.1 Windows

hello, i wonder how is string represent in R. if i have a string s= "hello", how can i refer to first character in the string s? also if i have s1 = "hello.1", s2 = "ok.1", how can i separate the s1 into "hello" "1" and s2 into "ok" and "1"? I have tried to use the substring function, but i don't where i can get the index

Hi all Is there any reason why the parameter i in a "for" loop ignores a value of zero? For example sim=c() p=.2 for(i in 0:5) {sim[i]=dbinom(i,5,p) } sim [1] 0.40960 0.20480 0.05120 0.00640 0.00032 In this example the quantile i= 0 was ignored since dbinom(0,5,p) [1] 0.32768 The same behaviour occurs if I use a while loop to perform the same calculation: sim=c() p=.2 i=0
