Re: [R] spaghetti plot - urgent

Hi Rosa, You pass a vector to ggplot, which expects a data.frame. I am sure you meant to do this: point7$y_point7 <- point7$beta0_7 + point7$beta1_7*point7$time + point7 $epsilon_7 ggplot(point7, aes(time, y_point7)) + geom_line() HTH Ulrik On Wed, 19 Jul 2017 at 20:37 Rosa Oliveira

Re: [R] STL - time series seasonal decomposition sensitive to data points?

I think this looks like a question about statistics. I suggest you review the documentation for the functions you are using and study the references to better understand the algorithms you are using. If you think the algorithms are not behaving according to theory and the packages are part of

[R] spaghetti plot - urgent

Hi everyone, I’m trying to do a spaghetti plot and I know I’m doing all wrong, It must be. What I need: 15 subjects, each with measurements over 5 different times (t1, ..., t5), and the variable that I need to represent in the spaguetti plot is given by: PCR = b0 + b1 * ti + epsilon B0, -

[R] STL - time series seasonal decomposition sensitive to data points?

Hi all, I am trying to analyse a time series data and want to make trend-season decomposition using STL approach in R. However I found the decomposition result seems to be sensitive to data points even with the robust option. More specifically, suppose I have a few years of monthly data. Using

I think the whole premise of this question is flawed. If you want to work with this string as data, then read it in from a separate file using readLines. If it is fixed data that you want to be part of your program, then invest the effort to escape the odd characters and be done with it. But

Necesito eliminar los datos de la COLUMNA"B" COMPRENDIDOS ENTRE EL 1-1-2016 y el 4-4-2016. Obviamente se entiende que son solo de la columna "B", DE MULTIPLES COLUMNAS de un data frame Queda más claro asi? Ahora, si al mismo tiempo, esos espacios en blanco se pudieses remplazar con NAN sería

Estimados Desde mi punto de vista, si los datos están en una base de datos es más simple trabajarlos en la base de datos, en caso de no poder modificar datos guardados se podría colocar en la consulta la parte sql que limpiaría los datos con unos simples if. Claro que cuándo los datos vienen

Primero asegúrate de que la columna "date" es de clase "fecha": datos$date <- as.Date(datos$date) Si quieres seleccionar las fechas anteriores al 4 de enero, sería, por ejemplo: datos$B[datos$date < "2016-1-4"] <- NA Si quieres seleccionar en un rango: datos$B[datos$date > "2016-1-2" &

Re: [R] Problem in shiny writing a .txt file

Is res.path usually empty? If the res.path directory is empty (i.e. dir(res.path) is an empty vector) the file.remove operation will remove the directory. This behaviour is documented in the help for file.remove. When your subsequent function tries to write to that directory it does not exist

Re: [R] Problem in shiny writing a .txt file

Hi Ana, The path is most likely wrong. How does f.texto() know the res.path? Do you manage to remove the old path and create a new one but f.texto() doesn't know? Not reasons for your problem, but curious: Why do you change the working directory? What is the intention behind appending
