similar to: comparison of these types is not implemented

All: I have a SQlite database where I have stored some verification data by date & time (cycle Z/UTC), lead_time as well as type, duration, etc. I would like to analyze & plot the data as monthly averages. I have looked at a bunch of examples which use some combination of zoo and aggregate, but I have not been able to successfully apply bits and pieces from the examples I have found. Any

Good evening! I don't know R, but I have to do this work for my diploma. So I'm sorry for the strange message below. Help me anybody decides this issues, please. a part of the code is: for (i in 1:133) { r_squared <- vector() sample_bank <- mydata[((i-1)*311+1):(i*311),] #return for bank return_bank <- diff(sample_bank[,4])/sample_bank[,4][-length(sample_bank[,4])] I've

As a long time nonlinear modeller, I always compute a quantity commonly referred to as R_squared or the coefficient of determination. However, I agree with other commentators, including those of several years ago, that one wants to be very careful about interpretation. In fact, I would say "DO NOT interpret". My usage of the quantity, which I tend to call "R_squared" but do

Buenas tardes, Estamos intentando hacer esta función, y sabemos que el bucle funciona (lo hemos testeado). Pero nos da este error ya en la primera línea: "Error in if (phen_tot$convergence[i][j] == '2' || phen_tot$r_square[i][j] <= : valor ausente donde TRUE/FALSE es necesario" Hemos evitado usar Tidyverse expresamente por la complejidad de la toma de decisiones del árbol;

Hola Carlos, Gracias por la respuesta. phen_tot es un data frame visualizado como tibble, y contiene (entre otras) las columnas "convergence", "r_square" y "maxlog10mfi". Y queremos crear nuevas columnas, como "use", "convergence_cor", etc. phen_tot$convergence debería ser un factor de si el modelo converge o no (levels: 1 y 2), pero tibble lo

Hi, everybody, 3 questions about R-square: ---------(1)----------- Does R2 always increase as variables are added? ---------(2)----------- Does R2 always greater than 1? ---------(3)----------- How is R2 in summary(lm(y~x-1))$r.squared calculated? It is different from (r.square=sum((y.hat-mean (y))^2)/sum((y-mean(y))^2)) I will illustrate these problems by the following codes:
