Dear all, Hope this question is not too trivial... In order to correct standard errors from an estimation of a fixed effects regression model y need to extract the vector of standard errors of the coefficients of a simple linear model estimated using lm(var1~var2+var3+var4) Unfortunately I can't find out the corresponding function. Thank you very much for your help. Uli -- Uli

Dear all, I'm looking for a way to solve a simple optimization problem with a nonlinear constraint. An example would be max x s.t. y = x * T ^(x-1) where y and T are known values. optim() and constrOptim() do only allow for box or linear constraints, so I did not succedd here. I also found hints to donlp2 but this does not seem to be available anymore. Any hints are welcome,

Dear all, I'm just trying to create plots for all variables in a dataframe (named "x") using the following: png() apply(x,2,hist) Just as intended, it produces one plot for each variable. Unfortunately, the main title of each graph is "Histogram of newX[,i]" instead of "Histogram of name of variable". This makes it impossible to assign the graphs to the

Dear all, I'm looking for a way to replace NA's with 0 for a number of variables which share the same ending and which constitute a subset of a data frame. Say, for example, there is > data <- data.frame(ax=c(1,2,3,NA,0) , bx=c(3,5,NA,5,1) , ay=c(5,NA,2,NA,0) , by=c(4,2,NA,2,1)) > data ax bx ay by 1 1 3 5 4 2 2 5 NA 2 3 3 NA 2 NA 4 NA 5 NA 2 5 0 1 0 1 I wish

Hi everybody! I've a large dataset, about 2 Mio entries of the format which I would like to import into a frame: <integer><integer><float><string><float><string><string> Because to the huge data amount I've choosen a binary format instead of a text format when exporting from Matlab. My import function is attached below. It works fine for only

Hello everybody, shame on me if I have overlooked something (CRAN, StatLib), but I think I've searched carefully. Maybe it's just too obvious to see for me (happens frequently). Is a function available that extracts multiple comparison of means from objects produced by "aov()" ? Sorry if the term is not correct, I translated from german word by word ("Multiple

Hi List, i am locking for a GUI for R. I have a Debian Woody 3.0 and running R 1.5.1. In office i am using SPSS 9.0 for several years now after Systat for short time and now i would use a statistic software under Linux at home. It seems that R could be that what i am looking for, but i have problems to understand how it works or better explained i would prefer using a good grafic interface.

Is there a way to have users of the samba server, but not add them by smbpasswd -a <UserID>? I want the samba server to be a domain member and the users to only authentic from the PDC. These are the steps that I have attempted: Users are in both the Windows domain and the UNIX NIS account 1. smbpasswd -j <Domain> -r PDC -U <admin> Joined the Domain 2. edited the

Hello, suppose I have a multivariate multiple regression model such as the following: > DF<-data.frame(x1=rep(c(0,1),each=50),x2=rep(c(0,1),50)) > tmp<-rnorm(100) > DF$y1<-tmp+DF$x1*.5+DF$x2*.3+rnorm(100,0,.5) > DF$y2<-tmp+DF$x1*.5+DF$x2*.7+rnorm(100,0,.5) > x.mlm<-lm(cbind(y1,y2)~x1+x2,data=DF) > coef(x.mlm) y1 y2 (Intercept)

Hello everybody, I frequently have to produce barplots from variables the natural variation of which is far away from zero. A typical range would be, say from -16 to -28. So, the following example should give an "honest" presentation: x<-c(-20,-22,-21,-28) barplot(x,beside=T,ylim=c(-18,-30)) But using anything else but "0" for the first element of ylim leads to strange

Hi, it looks like you have something really messed up on your system. The size of the file is 1243 bytes (from strace) but 0 bytes are being read. If you had no permission to read the strace would have looked like this: open("/etc/samba/smb.conf", O_RDONLY|O_LARGEFILE) = -1 EACCES (Permission denied) A quick look at the source code reveals: /etc/samba/smb.conf is opened in file_load

Hi, I posted this problem before in more detail (http://marc.theaimsgroup.com/?l=samba&m=104756899022766&w=2) but received no response. At the current state of Smaba 3.0 and Samba-TNG these two seem to be incomaptible. Samba 3.0 can't join a TNG controlled domain. I think this should affect a lot of installations as TNG as a controller and "stable" as file/printserver seem

I have the same problem. I can not boot a floppy disk. Once I did it but no longer I can do this.

This patch fixes a bug on systems with multiple connected network devices. As packet_peek uses all devices to receive data instead of a specific device. As the return value was never reset it was possible that packets from other devices were returned by packet_peek. That means that the ifindex did not match any ifindex of the specified devices the packet was never removed and packets for the
