Dear R users, I'm trying to save the results of separate logistic regression analyses of a dataset according to a categorical factor. For that, I first used a "by" function such as following : temp <- by( data, data$categorical.factor , function(x) summary( glm( formula = data$var1 ~ data$var2 , data = x , family = binomial("logit")))) and it worked perfectly well

Hello everybody, In order to predict income for different time points, I fitted a linear model with polynomial effects using BMA (bicreg(...)). It works fine, the results are consistent with what we are looking for. Now, we would like to predict income for a future time point t_next and of course draw the prediction interval around the estimated value for this point t_next. I've found the

Dear useRs, When I'm using Hmisc's latex() function with ctable=TRUE on a summary.formula with method="reverse" object and saving in a .tex file, the latter contains an unwanted empty line which makes compilation fail. Here is a brief example : library(Hmisc) test <- data.frame(a=sample(1:30,10),b=sample(c("good","bad","ugly"),10,replace=T))

Hello list, I have used scan function to import data into R. I have done some analysis and find strange results.

Hi the list, I am writing a R function that call a C function.

Hi everyone, I have built an R package and for the sake of speed I have decided to rewrite some part of the code in C++. In my original R code I use the pnorm, qnorm, rnorm, pgamma, dgamma, rgamma, rbeta and runif function. First I was thinking in going with the boost libraries, but I noticed the functions described above are available within the R.h header file (or is it Rmath.h?). So my

Hello everyone! First of all, please note that I'm working under Windows 7. I have written a Gibbs sampler in R and I'm now in the process of translating it in C++ to increase the speed. I'm relatively new to C++ and this question may be trivial, but my search so far have been unsuccessful. In my Gibbs sampler I am using some basic R functions (like the rep function for example)

Hi I have just started to have a look at R. I have used most stats software packages and can use perl, visual basic etc. I am interested in how well it handles lots of output e.g. tables or charts. How would you get lots of output most easily and quickly into a Word document? Sharon Snowdon ------------------------------------------------------------------------ - FIGHT BACK AGAINST SPAM!

Hello, I have problems running the R.matlab package. I work with R 2.3.1, under windows (using the Rgui). It seems that, even after loading the package, the "simple" functions such as writeMat() or readMat() are not recognized.
