similar to: can't find the error in if function... maybe i'm blind?

Dear everybody! take a<-c(5,3,NA,6). if(a[1]!=NA){b<-7} if(a[3]!=5){b<-7} if(a[3]!=NA){b<-7} if(a[3]==NA){b<-7} will alltogeather return Fehler in if (a[1] != NA) { : Fehlender Wert, wo TRUE/FALSE n?tig ist (or simularly). Somehow this is logical. But how else should I get out, whether a certain vector-component has an existing value? Thank you in advance! Yours, Mag. Ferri

I just started to write tiny functions and therefore I appologise in advance if I am asking stupid question. I wrote a tiny function to give me back from the original matrix, a matrix showing only the values smaller -0.8 and bigger 0.8. y<-c(0.1,0.2,0.3,-0.8,-0.4,0.9) x<-c(0.5,0.3,0.9,-0.9,-0.7,0.3) XY<-rbind(x,y) extract.values<-function (x) { if(x>=0.8|x<=-0.8)x

Hallo together, I am trying to use the nmkb() optimizer and I have problems using the function, as it causes the following error message Fehler (error)* in while (nf < maxfeval & restarts < restarts.max & dist > ftol & : Fehlender Wert (missing value)* , wo (where)* TRUE/FALSE n?tig ist (is required)* *translation Do I need to adjust the control ?

help Hello, I?m a statistic student in Austria and I have to do a survival analysis in R by using psplines as regressor. My problem is that I sometimes (I think it depends on the choose of the parameters) get a error message, but I do not know what it means. After that I tried the procedure with an example dataset R is providing. Although using the cancer dataset I also get this message. Input:

Hello list members I have a problem with modifying a data.frame. As an example given is a data.frame called ex : ex<-data.frame(id=c(1,2,3,4,5,6),obs=c(14,9,20,36,55,47),eff=c("A","A","B","C","C","C")) After that I would like to modify the object ex with the following short script: for (i in ex) { if(ex[i,3]=="A"||

Hi, I'am using the playwith library to write my own small GUI application.

Since it is not in my code, has anyone

The smbfs filesystem is mounted from a Windows 2000 Professional workstation. After

We have been using ZFS for user home directories for a good while now. When we discovered the problem with full filesystems not allowing deletes over NFS, we became very anxious to fix this; our users fill their quotas on a fairly regular basis, so it''s important that they have a simple recourse to fix this (e.g., rm). I played around with this on my OpenSolaris box at home, read around

Hi, I am currently working on fitting a mixture density to financial data. I have the following data: http://s000.tinyupload.com/?file_id=00083355432555420222 I want to fit a mixture density of two normal distributions.

--delete --force Won't Remove Directories With Dotnames rsync 2.6.9 Me, personally, I reckon this to be an irritant ... but perhaps (and having thought about this a bit I decided it's a good chance) this is an intentional and useful behaviour. But it's a nuisance if you call your --partial-dir .partial, as I happen to do, since now if you remove a directory which was aborted in

I want to use --min-size to copy just large files (and their necessary parent directories), but everything I've tried copies *all* the source directories, and creates them empty on the destination even if they don't have any big files in them. I only want the minimal directory hierarchies that contain the big files. This doesn't work: $ rm -rf /tmp/foo $ rsync -ai --min-size

Dear OpenSSH developers, OpenSSH setting non-blocking mode on its standard files creates serious problems. Setting non-blocking mode violates many of the semantics of how files are supposed to behave and most programs (and most, if not all, stdio libraries) are not prepared to deal with it. That wouldn't be a problem except that non-blocking mode is not a property of the file descriptor but

Hi there, I'm using RH7.2 (with the 2.4.9-30 kernal and it's required components) as a base for a server system running kernel 2.4.18. I've gone to this version to get around non-performing aic7xxx drivers in the stock 7.2 kernels, and updated gigabit ethernet drivers. I have a raid unit (Medea) attached to an Adaptec 3916, coming up as sdb. It has 2kb blocks, but the fault

Hi everyone, This is a strange problem I have been having. I'm not sure where the problem is, so I figured I'd start here.

Sure enough, once the file hit 17 gigs dd stopped and spit out an error (pandora bacula)# dd if=/dev/zero of=bigfile bs=1M count=50000 File size

Hi all, Is there a way to skip non-sequential lines using the "skip" argument in the scan function? E.g., I have a matrix with 100 rows and 1e7 columns. I open a connection and want to read only lines 5, 7, 9, etc [i.e., seq(5,99,2)] It might seem that the syntax to do this would be something like this (if only the "skip" allowed vectors in the same way colClasses does in
