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 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 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

Dear all, Within a larger script I use the following code to produce barplots for all variables contained in a dataframe "type3m": for(xn in names(type3m)) barplot(table(type3m[[xn]]), main = paste ("Barplot of", xn), width=0.75,legend.text=barnamesm, xlim=c(0,4),ylim=c(0,400)) The plots are produced and printed into a *.ps file. However, R gives an error

Greetings all, This is my first post to this forum, so please be kind. I am looking to integrate Asterisk as our primary voice mail server (IVS) for our NEC NEAX 2000 IVS. We currently use a 6-port Mitel system. The two communicate via analog TDM ports and a MCI serial connection. Is anyone familiar with setting up a NEAX 2000 with Asterisk as an IVR server? I know I would need six FXO and

Dear R useRs, I have a problem with nls.lm function of minpackl.lm package. I need to fit the Van Genuchten Model to a set of data of Theta and hydraulic conductivity with nls.lm function of minpack.lm package. For the first fit, the parameter estimates keep changing even after 1000 iterations (Th) and I have a following error message for fit of hydraulic conductivity (k); Reason for

Hi everyone,   I'm trying to do an Logistic Politomic Regression in R. Because I have my resposes variables and the aswer is 0 and 1 in 3 bacterial genes. Somebody know how to do this in R in a easy way?   Thank so much,   José Bustos Facultad de Ciencias Universidad Catolica Ssma.

Quick informal poll: what is everyone's favorite text editor for working with R?

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 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

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.

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

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)

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

Hello everybody, since I installed R-0.90.0 (Linux 2.0.25) I have problems with generating printable output with 'help()'. Default output to the terminal ('echo $PAGER' gives 'less') works o.k..
