Hi, Suppose I have a by b matrix which a and b are big numbers. How can I convert this matrix into a vector with length of a*b ? By column-wise or row-wise doesnt matter. My R version is 0.64.2.

Dear Help desk, What is the difference between glm and lm in R? I am so sorry the help pages dont really help me much since they dont have description how R handles the two.

Hello, I am wondering if someone can direct me to the syntax of the Generalised Additive Model in R? In Splus this is gam(formula, ... inputs would be pretty much the same as glm I suspect..) Any response on that (or what package should I grap) would be appreciated very much. Thanks, Peppy Adi-Purnomo -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

Hello, I am wanting to download the recent R update off the web. May I assume confidently that R package from the website is virus free?

hello, I have a very old R version which calculates anova table for a stream of outcomes say: 1,5,4,3,2,4,5,2 which are grouped into 4 blocks, say A,B,C,D, of 2 say namely X,Y What is the command in R 0.64.2 to do this? My very old R command is anova.table but this command is unkown in R 0.64.2 Thanks, Peppy -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

Does anyone know if the Dell Power Edge 1900 has an issue with multiport E1 cards? We've had this server running for a while now with 2 E1 cards. At first we tried to install an Openvox D210P card with two E1 ports but after a couple of kernel panics we thought that maybe the card was defective and we replaced it with two Digium TE120P cards. Now the customer needs a third E1 port and

Dear Users, I am trying to understand the inner workings of a repeated measures linear model. Take for example a situation with 6 individuals sampled twice for two conditions (control and treated). set.seed(12) ctrl <- rnorm(n = 6, mean = 2) ttd <- rnorm(n = 6, mean = 10) dat <- data.frame(vals = c(ctrl, ttd), group = c(rep("ctrl", 6), rep("ttd",

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 R-listers, I have a little problem with a boxplot and I hope you can help me figuring it out. I'll try to make up some data to illustrate the issue. Sorry, if my procedures look naive, but these are my first steps in R. Any comments and/or suggestions are very welcome. let's create a vector var1: var1 <- rnorm(100) and 5 five logical vectors. In this case the vectors don't

Dear R users: I am not entirely convinced that clogit gives me the correct result when I use pspline() and maybe you could help correct me here. When I add a constant to my covariate I expect only the intercept to change, but not the coefficients. This is true (in clogit) when I assume a linear in the logit model, but the same does not happen when I use pspline(). If I did something similar

Hi R-fellows, I am trying to simulate a multivariate correlated sample via the Gaussian copula method. One variable is a binary variable, that should be autocorrelated. The autocorrelation should be rho = 0.2. Furthermore, the overall probability to get either outcome of the binary variable should be 0.5. Below you can see the R code (I use for simplicity a diagonal matrix in rmvnorm even if it

Hello, My problem is that I would like to merge multiple files with a common column but merge accepts only two data.frames to merge. In the real situation, I have 26 different data.frames with a common column. I can of course use merge many times (see below) but what would be more sophisticated solution? For loop? Any ideas? DF1 <- data.frame(var1 = letters[1:5], a = rnorm(5)) DF2 <-
