Hello, I am new to Ubuntu (Linux in general) and I am trying to install R: so far, I am stuck. I have followed the instructions at the CRAN website with little luck. I read an exchange about the same issue posted before, but did not give me enough information to solve things by myself, hence, this email. Based on the former exchange I read, I am trying to include enough information to see if

It is there any implementation of a Least Squares Restricted Estimator for a single equation in R? I have seen in the list some examples in which linear constraints are embedded within the equation, but let's say that I have a large number of coefficients (on factors) that I want them to sum up to 0 (so I can include an intercept, the full set of factors, and avoid the dummy trap). Is there

Dear Users, I already posted this question: it either went unnoticed, or it is to basic (if this is so, please sent me a hint). I would like to know if there is a way to add a common legend to an arrangement of plots. In the example below, I get four plots in my device. each one has a density for 1995 and one for 2006. I have found that using legend or smartlegend I can add a legend to each plot,

Dear All: I need advice about efficient looping/vectorization. I am trying to bootstrap a regression model with one lag of the dependent variable in the RHS. Specifically, let error^b_(t) be the bootstrapped error of the regression y_(t) = gamma y_(t-1) + beta x +error_(t) at time (t), y_(t) is the original dependent variable, and y^b_(t) the bootstraped y_(t) using parameter estimates gamma and

Hola, buenas estimados. Acabo de instalar, después de algún tiempo,  R versión 4.3  y Rcommander en Manjaro Linux, 6.3.5  Y me he dado cuenta que no existe la opción de crear un Nuevo conjunto de datos. ¿eso es así ahora? Muchas gracias por su tiempo. Saludos. -- Ps. Félix Pérez Villoria Centro Kumon & Ayudantía Pedagógica. https://www.ayudantiapedagogica.cl General Ordóñez 30 oficina

Hi, everyone I've been trying to make a scatter plot of POSIXct format data to see the difference between two start time. Like X: [1] "1995-05-26 19:00:00" "1995-05-27 01:00:00" "1995-05-27 07:00:00" [4] "1995-06-29 01:00:00" "1995-06-29 07:00:00" "1995-06-30 13:00:00" [7] "1995-06-30 19:00:00" "1995-07-01

Hello! I've been trying to get this right for quite a while now and fear there is an easy solution I just don't see. I did not have this problem in Linux, and I searched r-help and Google but did not find a solution, but of course I am grateful for and resources I might not have found our not understood yet. I try to parse a time stamp with time zone. I essentially just want to parse the

Hello: As someone making the move from STATA to R, I'm finding it difficult at times to perform basic tasks in R, so forgive me if I've missed an obvious and easily obtained solution to my problem. I've searched the help guides and the archives and have not been able to find a solution that works. I have a data frame with thousands of observations that looks something like this:

I am trying to learn how to format Ascii data files for scan or read into R. Precisely for a quickie project, I found some code (at end of this email) to do exactly what I need: To cluster and graph a dendrogram from package (stats). I am stuck on how to format a text file to run the script. I looked at the dataset USArrests (which would be replaced by my data and labels) using UltraEdit. That
