Hi, I have a suggestion for the fonction arima and arima0. I think you should not call the constant an intercept because it creates confusion. It is not really an intercept but a mean. For an AR(1) the intercept mu should be defined as: X(t)=mu + phi X(t-1) + e(t) What you call intercept mu is rather defined as (X(t)-mu) = phi (X(t-1)-mu)) + e(t) which is not a common way to define an

Hi, There is a small bug in the kernel() function. Everything is fine when we use the format: kernel("name",m,r) but if we want the first argument to be a vector, which is useful is we are interested in using a method not implemented in kernel(), the default value of m is wrong. For example, if we do: s <- rep(1/11,6) k <- kernel(s) we get the error message Error in

Hi all, I found a discrepancy between the sum() in R and either a sum done in C or Fortran for vector of just 5 elements. The difference is very small, but this is a very small part of a much larger numerical problem in which first and second derivatives are computed numerically. This is part of a numerical method course I am teaching in which I want to compare speeds of R versus Fortran (We

My simple functions were to compare the result with the gfortran compiler sum() function. I thought that the Fortran sum could not be less precise than R. I was wrong. I am impressed. The R sum does in fact match the result if we use the Kahan algorithm. P. I am glad to see that R sum() is more accurate than the gfortran compiler sum.

I have a suggestion for kernapply for ts objects. When we choose the option circular=F, the returned series don't have the correct dates. The removed dates are all at the beginning instead of half at the beginning and half at the end. It is particularly useful when we need to smooth the series (or remove a trend using a filter) before estimating a model (like in macroeconomics) or simply

Hello. I have been trying to find an answer to a problem that has plagued our systems. I am trying to upgrade from 3.0.22 to 3.0.23c. I have been able to compile, but when I go to join it to the AD domain, I keep getting this familiar error that many others have noted but have not posted many solutions to. arcdba-> ./net ads join -U Administrator Administrator's password: Using short

Hello Dan, > The Linux distribution I uses is a Red Hat EL-AS 3 (update 4) and the > platform is an old LION (HP rx4610) (4xIA64 - 666 MHz, 1GB memory). As we say in france, "Les cordonniers sont toujours les plus mal chausses", and in your native language: "Nobody is worse shod than the shoemaker''s wife". For the moment, I have nothing else than this Lion platform. I''m waiting after a Tiger system for the end of this month. Soon, I would be able to open a zoo. Philippe. ---------------...

Hi everybody, I'm using a FreeBSD 6.1 box running Samba-3.0.23c_2,1 from the ports tree, authentification is provided by two MS PDC (kdc1 and kdc2, the domain is called PARIS). Previous versions of Samba (<3.0.23c) used to work perfectly but since I upgraded to 3.0.23c, I have very disturbing timeouts problems affecting winbind. A simple "smbclient -L <myserver> -U

Hi all, I am looking for a function similar to mclapply() that would work with GPU cores. I have looked at all possible packages related to GPU computing but they are mainly providing functionality for big dataset or big matrices. I use mainly mclapply to speed up simulations by running several simulations in parallel, which works nicely. Is it possible to do the same with a multicore GPU? I

Install the gmp package, run your code, and then try this: bu <- gmp::as.bigq(u) bs4 <- bu[1] + bu[2] + bu[3] + bu[4] + bu[5] s4 <- as.double(bs4) s1 - s4 ## [1] 0 s2[[2]] - s4 ## [1] 7.105427e-15 s3 - s4 ## [1] 7.105427e-15 identical(s1, s4) ## [1] TRUE `bs4` is the exact sum of the binary rationals in your `u` vector; `s4` is the closest double precision to this exact sum.

Hello, We recently upgraded to the latest Samba3 version v3.0.23c. If the Samba system and the AD belong to the same domain, I am able to perform a 'net ads join' by supplying either a 'Domain Admins' or a 'Domain Users' credential. However if the Samba system and the AD belong to different domain, I can perform the 'net ads join' by supplying a 'Domain

I've rolled up R-2.12.2.tar.gz a short while ago. This is an update release, which fixes a number of mostly minor issues, and one major issue in which complex arithmetic was being messed up on some compiler platform. You can get it from http://cran.r-project.org/src/base/R-2/R-2.12.2.tar.gz or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will

Hello, I am running a fileserver with smbd here. The server is a 64bit 2.8 GHz Celeron D with 2GB RAM, running 64bit Debian, Samba version 3.0.23c. It is running as a pure fileserver so its only CPU load is serving files. The client I am doing the tests from is WinXP Pro SP2. It is connected via Intel e1000 gbit ethernet (both the server and client use e1000 chipsets). I have done a raw tcp

Hello: The example "integrate(dnorm,0,20000)" says it "fails on many systems". I just got 0 from it, when I should have gotten either an error or something close to 0.5. I got this with R 2.12.0 under both Windows Vista_x64 and Linux (Fedora 13); see the results from Windows below. I thought you might want to know. Thanks for all your work in creating

Hi all I have a network with a Windows 2003 AD (10.10.10.5) and a Samba 3.0.23c (10.10.10.8). I want Samba to join the domain and get it's user/group/permission info from my Windows 2003 server. I have followed http://samba.org/samba/docs/man/Samba-Guide/unixclients.html#ch9-adsdc And it seams to join and work with wbinfo/getent/"net ads join/info/status". When I try to login with
