Good morning, I wrote a little code in R which has to show two graphs but I can get only one. How can I adress the graphs in two files? Second, I'd like, always in the same code, to add a legend to a graph. Better, I'd like to put in such a legend a new item whose color could remind the colour ol the columns it refers to in the plot. I wrote: leg.txt<-c("control

Hello, I would like, if it is possible, to compare the effect of a variable across regression models. I have looked around but I haven't found anything. Maybe someone could help? Here is the problem: I am studying the effect of a variable (age) on an outcome (local recurrence: lr). I have built 3 models: - model 1: lr ~ age y = \beta_(a1).age - model 2: lr ~ age + presentation

Hi all, im triyng to implement a bayesian model with R and c++. I have a strange problem. I can't reproduce the error with a small script and then i post the original one. The problem is after the line for(MCMC_iter2=0;MCMC_iter2<thin;MCMC_iter2++) For the first 34 iterations all work fine, after, all the simulations of mu_acc_P return an "nan". If i delete the line

Hi, I have data in the following form: index count -7 32 1 9382 2 2192 7 190 11 201 I'd like to get quantiles from the data. I thought about something like this: index <- c(-7, 1, 2, 7, 11) count <- c(32, 9382, 2192, 190, 201) quantile(rep(index, count)) It answers correctly, but I feel it's wasteful especially when count is

Gracias chicos por sus opiniones y recomendaciones. Como dice Javier Rubén, justo lo que quiero es que los chicos aprendan bien los fundamentos de un lenguaje de programación orientado a objetos para que no solo copien el script de una librería, corran y ya.

Hi All! Been quite a few years and lots of water under the bridge but here I am back! I have a customer that has now decided they need a bit more bandwidth over and above their fixed line! They are not in a good area for ADSL because of copper theft and being a bit to far from the closest DSLAM! They have installed a wireless link and I have made certain that put it behind my simple iptables
