Hi All: I'm running Mandrake 8.1 (downloaded) and the install went fine. Configuring Samba however is another story. I get the message "could not connect to host - localhost" on the Linux box. I cannot see the network from the Linux system. The Linux system is visable from Win'98SE as are the shares but I cannot access them "password is incorrect". This does not

Hi All: I think I've finally nailed this one down. Here was the original problem: > I'm running Mandrake 8.1 (downloaded) and the install went fine. > Configuring Samba however is another story.

Hi, According to ChangeLog someone "(bal)" removed -{enable/disable}-suid-ssh from configure (dating from 2002/06/07). Don't know the reason, probably this has something to do with PrivilegeSeparation. Consequence is: Users with UID != 0 are no longer able to allocate privileged ports, sshd answers "Rhosts Authentication disabled, originating port will not be

Hi, I have a daemon process which is changings things in the system only the superuser should be allowed to change. Lets call it "riskyd". Users use a frontend on the same machine (lets call it "risky"). risky is a SUID program which talks to riskyd by binding to a privileged port, then connecting to riskyd on localhost. riskyd cheks that the connection is coming from

Hello everyone, What is the simplest, most RELIABLE way to import data from MS EXCEL (.xls) format to R? In the past I have used the read.xls() function from the xlsReadWrite package, however, I have been wrestling with it all afternoon long with no success. I continue to receive the following error message: > {widge<-read.xls("F:\\Classes\\Z1.Data\\stat.3010\\WidgeOne.xls", +

Hi everyone, I have the following: sqldf("select Premie,count(tpounds) N,avg(tpounds) Avg_Weight, stddev_samp(tpounds) StdDev from children group by Premie having !is.na(Premie)") sqldf() does not like the !is.na(Premie) specification. How does one exclude a "missing" group in an aggregated query using sqldf()? Thanks! Dan [[alternative HTML version deleted]]

Hi everyone, I understand the process of obtaining the internal integer codes for the raw values of a factor (using as.numeric() as below), but what is the best way to obtain these codes for the levels() of a factor (since the as.numeric() results don't really make clear which code maps to which level)?

Hello everyone, I am trying to add the following text (in proper notation) to a graphic using expression(). X-bar (with a subscript of cv) = XX. Note: Ideally "cv" would be a subscript, but it doesn't have to be. I have the following code: > text(625,.012,expression(bar(X)cv = 552.01)) Error: unexpected symbol in "text(625,.012,expression(bar(X)cv" I have also

Hello everyone, I have the following call to sapply() and error message. Is the most efficient way to deal with this to make sum(!is.na(x)) a function in a separate line prior to this call? If not, please advise. N.Valid=sapply(x,sum(!is.na(x))) Error in match.fun(FUN) : 'sum(!is.na(x))' is not a function, character or symbol Thanks! Dan [[alternative HTML version deleted]]

Hi, since I switched from SSH 1 to OpenSSH 2.9p2/2.9.9p2/3.0p1 Snapshot I suffer from awfully slow connection performance. Once the connection is established, performance is perfectly ok. Client Server (protocol 2 only) # time ssh -p 22222 xx id # time sshd -d -p 22222 real 0m13.340s real 0m13.900s user 0m7.860s

Is there some way to add a maildir folder to a mbox hierarchy? My folders are all mbox, but I want to migrate some client-side mail from a client (PMMail2000) that stores messages as individual files, and it might be easiest just to dump all the files into a maildir directory with suitable naming.

Hi everyone, Any ideas on troubleshooting this memory issue: > d1<-read.csv("arrears.csv") Error: cannot allocate vector of size 77.3 Mb In addition: Warning messages: 1: In class(data) <- "data.frame" : Reached total allocation of 1535Mb: see help(memory.size) 2: In class(data) <- "data.frame" : Reached total allocation of 1535Mb: see

Hi everyone, How does one place an object name (in this case a vector name) into another object (while essentially masking the values of the first object? For example: > JOBSAT<-rnorm(40) > > CI<-function(x,alpha){ + result<-cbind(x,mean=mean(x),alpha) + print(result) + } > CI(JOBSAT,.05) I want this to return: Variable mean alpha JOBSTAT 0.02844131 0.05

Hi, attached please find some patches for ReliantUNIX. This was tested under Reliant UNIX V5.43C40 with Compiler CDSDEV V2.0C00. Here is what I did: - there is a common misunderstanding how to use /usr/libucb/libucb.a: There are some library functions only in libucb.a under ReliantUNIX, so one needs to bind it. The problem is: there are some other functions in this library you should never

Hi all, I want to select all variables in the data.frame with a name that includes are certain string. Something like the following: merge3[,names(merge3) %in% c("Email","Email.x")] But there are too many variations on the Email variable names to list them all. Can anyone advise? Thanks! Dan

Hi all, I have a situation where I have 16 bins. I generate a random number and then want to know which bin number the random number falls in. Right now, I am using a serious of 16 if() else {} statements which get very complicated with the embedded curly braces. Is there a more efficient (i.e., easier) way to go about this? boundaries<-(0:16)/16 rand<-runif(1) Which bin number (1:16)

Hello everyone, I am attempting to use the %in% operator with the ! to produce a NOT IN type of operation. Why does this not work?

Hello everyone, Is it possible to specify a 2 line y-axis label on the same lef-hand side y-axis?
