I have a Date x Stock (223 x 520) matrix of "trading volume". I can calculate a 5-day (past) average in about 1 second using: R> apply(vol, 1, filter, filter=c(0, rep(1/5,5)), sides=1) I would like to do the same with a 5-day median, e.g.: R> mymed <- function(x, n=5) { R> r <- rep(NA, length(x)) R> for (i in (n+1):length(x)) r[i] <- median(x[i-(1:n)]) R>

formatC() is great for formatting numbers! But it would be even better if it could optionally insert commas (or semicolons), e.g. R> formatC(1234567.89, digits=2, format="f", commas=T) [1] "1,234,567.89" Here's a snippet of code that does that, which could more or less just be inserted into at the end of formatC if any R-core guru were so inclined. "r"

In R-1.5.0pre (2002-04-08) on Solaris 2.6, the window that X11() creates has a title like: R Graphics: Device 2 (ACTIVE) o iyeP )( y except the funny characters at the end have umlauts and other accents (i.e. extended ASCII characters), and they may be different each time X11() is invoked. There is no loss of functionality; it just looks a little ugly. I saw this behavior in R-1.3.?, it

I'm trying to set up a Linux-based dialin server on our company network. I'd like to have PPP authenticate using winbindd, if possible. I feel like I've almost gotten it to work, but I can't quite get there. Files: /etc/pam.d/ppp: #%PAM-1.0 auth required pam_nologin.so auth sufficient /lib/security/pam_winbind.so account required

I sent a message to <r-announce at stat.math.ethz.ch> last Thursday ("New package: colSums"), and still haven't seen it echoed on r-help or on the web archive (in fact there is no r-announce web archive for 2002). Is something broken? Did I need to use <r-announce at lists.R-project.org> instead? -- -- David Brahm (brahm at alum.mit.edu)

Under R-1.5.0 on Solaris 2.6: R> prettyNum(123456789, big.mark=",") [1] ",123,456,789" and that bad behavior (leading comma) spills into formatC as well: R> formatC(123456789, digits=0, format="f", big.mark=",") [1] ",123,456,789" Looks to me like a bug in src/library/base/R/format.R, in function prettyNum: B.[i.big] <-

Hello, I have been trying to connect a Rails application to DB2 database. Based on information found on the web it doesn''t seem to be possible. Can some confirm the state of DB2 support with Rails?

I'm sure this is something simple, but I can't figure it out. After a printing system upgrade, my old PDF-writer script (which acted as an lp input filter) stopped working. I took this as an opportunity to rewrite it to work straight from Samba. But I'm having an odd problem -- I can't find Samba's job file. Here's the entry: [pdf2] path = /export/spool

Okay, this is a recurring problem that really has me frustrated. I have a samba server that's using security=server. There are four people who use it. It works fine for three of them, but the fourth one gets endlessly prompted for his password and is never allowed to log in. All are from NT 4.0 clients. What's really puzzling is that when I look at the log at debug level 2, I get the

Before I go and try to write something myself, I'm curious if anyone has a script that they're using for setting and clearing the MWI on a legacy PBX. I need to pick up a Zap channel and dial #63XXX to set the MWI, or #64XXX to clear it, where XXX is the extension number. One complication is that I've got a couple dozen extensions to handle the MWI for, and only four channels to work

Hi, I'd like to reduce the size of the samba binaries. smbd for instance is about 1.5 meg, which is way to much if you ask me. Is there a way to create smaller binaries, maybe by compiling differently? thanx, Dennis ===== __________________________________________________ Do You Yahoo!? Yahoo!

I'm running Samba 2.2.3 with winbind for authentication. Much to my surprise, I found I had a need to connect an MS-DOS system to the network. I'm using MSCLIENT to do so. I can successfully log into the domain and map drives on Windows NT servers, but I'm having trouble mapping Samba shares. Examining the log shows that the DOS machine is apparently trying to connect with a username

Hi I actually had this same problem when running up samba originally. Check that the user has a valid unix acount and that you have added that to the folder share/valid users section.

Howdy, We occassionally get the following error when running our nightly backups: rsync error: received SIGUSR1 or SIGINT (code 20) at rsync.c(229) This happens more on one or two machines than on any of the others. We've looked high and low to see if we're mistakenly sending these signals, but nothing is that we can find. Does anyone know what this might be from? Is it the server

One of our employees is having an odd problem with Adobe Photoshop. Files he saves with Photoshop are saved with permissions 777, completely ignoring both the create mask and the default ACL for the directory. Files he creates with other programs have the correct permissions. This has me stumped. It appears I can reproduce the problem at will. Client is Windows NT 4.0 SP6a and Adobe Photoshop
