similar to: installation of R on Linux

I am a new user of Linux (long time user of Windows) whose only training is from books, articles, and just playing with Linux. I have built and installed R from source, and also installed from RPMs (SuSE). I am wondering where in the file system experienced users of R and Linux typically install R. Are there any conventions, or any reasons to choose one location over another? I know that

Hi Dan, sorry for the precedent email, I created a csv file of only 1000 records by mistake, that's why R has only read 1000 records. regards Anna ----- Messaggio Inoltrato ----- Da : "a.martino at crismaitalia.it" <a.martino at crismaitalia.it> A : "Daniel Nordlund" <res90sx5 at verizon.net>,<r-help at stat.math.ethz.ch> Oggetto : RE: [R] importing

I am trying to work my way through the book "Singer, JD and Willett, JB, Applied Longitudinal Data Analysis. Oxford University Press, 2003" using R. I have the SAS code and S-Plus code from the UCLA site (doesn't include chapter 8 or later problems). In chapter 8, there is a structural equation/path model which can be specified for the sem package as follows S <- cov(al2)

Say I have a dataframe like this: df <- data.frame(cbind(c(1,0,0,1),c(0,1,0,0),c(0,0,1,0))) names(df) <- c('a','b','c') I would like to create a factor in a new column, where the factor values are taken from the column names, like this: > df2 a b c f 1 1 0 0 a 2 0 1 0 b 3 0 0 1 c 4 1 0 0 a How would I do this? Thanks, Dan Daniel Nordlund Bothell, WA USA

Hello, I wanted to ask help about importing sas datasets. 1)I tried with some functions as read.ssd (foreign package), but it doesn't import the file if the length of the variables' names are longer than 8 bite (it has to conform to the 6 version). 2)I then tried with the sas.get function (Hmisc package) but with the command: c<- sas.get(lib="c:\\ghan",

If I have two matrices like x <- matrix(rep(c(1,2,3),3),3) y <- matrix(rep(c(4,5,6),3),3) How can I combine them to get ? 1 1 1 4 4 4 1 1 1 5 5 5 1 1 1 6 6 6 2 2 2 4 4 4 2 2 2 5 5 5 2 2 2 6 6 6 3 3 3 4 4 4 3 3 3 5 5 5 3 3 3 6 6 6 The number of rows and the actual numbers above are unimportant, they are given so as to illustrate how I want to combine the matrices. I.e., I am looking for

I am trying to resolve a problem I am having with running the rattle package on two different Windows 7 x64 systems. It appears to be a problem with my two specific systems, because others on Windows 7 x64 systems aren't complaining about this problem. What I am looking for is a method for trying to determine the source of the problem. Here is what I am experiencing. I had Rattle running

I encountered the following problem in R-2.4.0 for Windows binary downloaded from CRAN (data from R-help post by Ethan Johnsons). I was also using the contributed binary Rblas.dll for Intel P4 chip. The problem doesn't occur with the default Rblas.dll. x=c(3.05176E-05, 0.000457764, 0.003204346, 0.0138855, 0.04165649, 0.09164429, 0.1527405, 0.1963806, 0.1963806, 0.1527405, 0.09164429,

I am using R-2.10.1 binary from CRAN on a WinXP Pro system. I also use SAS v9.2 on the same box. I just started using the SAS ODBC driver that comes with version 9 of SAS. I have been able to set up an ODBC source for SAS datasets using the driver, and then with RODBC I am able to read a sample SAS dataset. > library(RODBC) > ch <- odbcConnect('sasodbc', believeNRows=FALSE)

I am running Ubuntu 7.10 and R-2.6.0, and I am having trouble updating packages. There appears to be a problem involving gfortran. For example, here is the output of an attempt to update the Hmisc package. * Installing *source* package 'Hmisc' ... ** libs gfortran -fpic -g -O2 -c cidxcn.f -o cidxcn.o gfortran -fpic -g -O2 -c cidxcp.f -o cidxcp.o gfortran -fpic -g -O2 -c

I have been asked to look at options for doing relative risk regression on some survey data. I have a binary DV and several predictor / adjustment variables. In R, would this be as "simple" as using the survey package to set up an appropriate design object and then running svyglm with family=binomial(log) ? Any other suggestions for covariate adjustment of relative risk

Running v5 64bit on a Dell 1950. A cluster of 3 DB machines, identical hardware. One of them suddenly became slower 2 weeks ago. tar -zxf with a large file on this machine takes 1.5 minutes, but takes only 10 seconds on any of its siblings. CPU usage seems high while untarring, with lots of user and sys cycles being used, but almost no wait cycles. It doesn't matter whether I untar on a

I have been working through the book "Applied longitudinal data analysis: modeling change and event occurrence" by Judith D. Singer and John B. Willett. I have been working examples using SAS and also using it as an opportunity for learning to use R for statistical analysis. I ran into some difficulties in chapter 8 which deals with using structural equation modeling. I have tried to
