Does anyone know a simple way to insert an extra row into a matrix or data frame, thus increasing the dimensions.

Hello, 1. After I generate a 100x50 matrix by x3<-matrix(0,100,50);for (i in 1:100) {x1<-rpois(50, mu[i]);x2<-x1; x2[runif(50)<.01]<-0; x3[i,]<-x2}, 2. I want to calculate means and sample variances of each row and create a new matrix 100x2; 3. I then want to repeat above procedure 500 times so that eventually I will have 500 100x2 matrices. Would someone mind helping me to

I have successfully, by now, installed a samba server. I can log on from win98 and 95 computers. I can see the shares and use some of it. There are a couple of shares [Home] [Document] I can browse the share and a user, "Mats", can read and write copy and so on in /home/Mats, so obviously the server recognizes the user as the Linux user with the same name.

Hi, Does anyone know if R has the functionality to calculate a simple moving average. I cant seem to find it in the help menu. thanks, Wayne Dr Wayne R.

Dear all, Is there a test in R for the randomness of a sequence of observations (e.g. to test the random number generator)? Specifically I am looking for autocorrelations which are not necessarily linear in nature, which the acf function does not seem to be flexible enough to detect as it tests for linear autocorrelation. Thanks in advance, Paul.

Hi there fellow R-users, I'm stuck on this seemingly trivial problem. All I want to coerce a character string into a command. For example: x<-rnorm(20) y<-rnorm(20) str<-"lm(y~x)" I want to evaluate the "str" command. I have tried eval(as.expression(str)) But it doesn't seem to work. I am aware of the call command, but for reasons I won't go

Hi there fellow R-users, Does anyone know if there exists a package for associated rules data mining (market basket analysis) in R. I have tried searching CRAN but with no luck.

Hi! I've just begun writing a program that searches for the minimum of a function with golden section search. In order to do this in a nice way I need a function that takes a function name and an argument and returns the function value for that argument, i .e just like Matlab's 'feval'. Is there any? Thanks before hand! Best regards, Fredrik Thuring, Codan Insurance A/S

Hi there fellow R-users, Can anyone tell me if there exits an R package that deals with serial correlation in the residuals of an lm model. Perhaps, using the Cochrane Orcutt or Praise Wilson methods? Thanks, Wayne Dr Wayne R.

Hi! I'm trying to start a credibility estimation study with a coule of data sets that are created for SAS. The data sets are saved as ".sas7bndx" and ".sas7bdat". I've tried reading them to R with the function 'read.xport' but this returns the error message 'Error in lookup.xport(file) : unable to open file'. Are there any other functions that one

Hi! I have a few questions concerning reading of tables from R to other programs. My main question is if it’s even possible to read a table created in R (with the functions data.frame and save) to Excel (or maybe SAS) and if so how does one do this? If I just mark the table in R and copy-paste to Excel the whole table ends up in one single cell, (of course). My goal is to

Hello there fellow R-users, I am using the RODBC functionality to query a database. I am trying to read in a columns of strings which have a character field lengths greater than 255. The data.frame that I recieve back from the RODBC query only contains the first 255 characters (the rest having been truncated). Any help on how to solve this problem would be greatly appreciated.
