Re: [R-es] Promedio elementos vector

Hola Manuel, Utilizando el conjunto de ejemplo que enviaste, la matriz resultante con las medias no era "character" era todo numérico. Supongo que habrás obtenido "character" porque tu matriz de trabajo de partida tendrá algún elemento como character ... Se puede incluir una función

[R-es] Promedio elementos vector

Estimado Carlos: Di por solucionado el asunto de referencia, sin embargo me topé con un problema, y es que los valores que da la matriz con los promedios son texto, y no encuentro la manera de convertirlos a número, y así poder usarlos con otras cantidades. ¿Me puedes ayudar nuevamente para

Re: [R] Plotrix install bug with Umlauts in path name

Hi Andre, This sounds to me like a locale problem. Installation of a package is performed by functions like install.packages and as long as the package has passed CRAN checks, the contents shouldn't matter. I've copied this to the list as I'm sure that one of the experts in this area will have an

[R] Bias-corrected percentile confidence intervals

Hi folks, I'm trying to estimate bias-corrected percentile (BCP) confidence intervals on a vector from a simple for loop used for resampling. I am attempting to follow steps in Manly, B. 1998. Randomization, bootstrap and monte carlo methods in biology. 2nd edition., p. 48. PDF of the

Re: [R] Statistical / data mining methods in R and not in SAS?

David's reply is far more comprehensive, but it may be worth adding that new "data mining" packages are being added almost daily to R software repositories (CRAN, github, etc.), so that anything one would say about this becomes almost instantly outdated. e.g. from a post 4 days ago here from Nan

[R] {nlme} Question about modeling Level two heteroscedasticity in HLM

Hello dear uesRs, I am working on modeling both level one and level two heteroscedasticity in HLM. In my model, both error variance and variance of random intercept / random slope are affected by some level two variables. I found that nlme is able to model heteroscedasticity. I learned

Estimado David Contreras Lo primero no es sobre R, sino sobre el lenguaje, es lo mismo pero si nombra las variables como A, B, y C, la lectura es mucho más simple para el ojo humano y encontrar el error (luego colocar un nombre casi real). Es un problema simple, con muchas posibles formas para
