Estimados Usuarios-R: Estoy convirtiendo un programa en Matlab a R. El original lo saqu de: Lai, M., & Poltera, Y. (2009). Lecture with computer exercises: Modelling and simulating social systems with matlab. Tech. rep., Swiss Federal Institute of Technology (December 2009). 27. Ahora estoy convirtiendo la siguiente funcin: function sizes = gridsizes(N,varargin) % gridsizes(N) calculates

Hello, I am drawing contour lines for a function of 2 variables at one level of the value of the function and want to include a small arrow in any direction of increase of the function. Is there some way to do that? Below is an example that creates the contour lines. How do I add one small arrow on each line in the direction of increase of the function (at some central point of the contour

ggplot2 ------------------------------------------------------------ ggplot2 is a plotting system for R, based on the grammar of graphics, which tries to take the good parts of base and lattice graphics and avoid bad parts. It takes care of many of the fiddly details that make plotting a hassle (like drawing legends) as well as providing a powerful model of graphics that makes it easy to produce

Dear all, as you can see from the code I want to create *a panel of 11 contour plots through a iteration process*. I found a thread that address the issue of plotting many contour.plots in the same device, but it does not address my problem! I emphasize that the 11 contour plots must be appeared in the same device through an iteration process and NOT individually! par(mfrow=c(4,3)) # I want them

Hola a todos Estoy aprendiendo a trabajar con el paquete de RMySQL, y a la vez con bases SQL, así que a lo mejor no es tan complicado. Quiero agregar valores, que genero en R, a una tabla de SQL más o menos la idea es: > ssql<-"INSERT INTO tabla1 (variableA, variableB) VALUES (''valor1'',''valor2'')" > dbSendQuery(conec, ssql) pero

Buenas, Tengo un dataframe con 64.000 observaciones llamado Datos y las variables "Id.Producto","Fecha"y "Rating" . La variable fecha tiene el formato: 2016-12-28 (ymd). Quiero crear la variable: "Rating.Semanal" - Esta variable tiene que ser la media agregada por "Id.Producto" de la variable "Rating", solo teniendo en cuenta

Sebastián No se para que vas a usar los datos, pero yo no usaría ceros cuando el dato no esta disponible ( me saltearía el último paso de la rutina que te mando). Seguramente hay mejores y mas eficientes maneras de hacerlo en R pero esta es una quizás no muy elegante: original <- matrix( c(1 ,1 ,1, 1, 223, 2, 1, 224, 3, 3, 447, 1, 78, 335.75, 8, 2901, 186.3, 2, 2901, 886.18, 3, 2901,

Buenas tardes, Estoy intentando conseguir la media de la variable "numerocaracteres" por "producto" de mi base de datos, datos. Lo estoy haciendo con la función aggregate de este modo: AggregatedData<- aggregate(numerocaracteres ~ producto, data=datos, FUN=mean) El problema me viene porque quiero utilizar una variable de ponderación de modo que para construir la media

Hola a todos, a ver si me pueden echar una mano que estoy atascado.tengo estas dos tablas: > head (intento1)      codigo     categoria         talla             num1       1                904                400               12       1                904                460               13       1                904                470               44       1                904  

Buenas, Tengo un monton de variables que quiero meter en un data.frame. Las variables las he ido extrayendo de la siguiente manera for(i in 1:240) { #saco el inicio de cada refrigeracion aux1 <- paste("inicio.refri", i, sep = ".") assign(aux1,datos[which.max(datos[,109+i]),"LogDateTime"]) } Y quiero buscar una funcion que me permita meter esas 240

Es posible agregar ruido a una serie de tiempo Tengo series de tiempo que tienen un comportamiento funcional, quisiera agregar ruido para que parezcan señales mas reales. Normalmente las series de tiempo se suavizan a traves de filtros, es posible hacer el proceso inverso con algun paquete de R Gracias por la atención CARLOS ANDRES PEREZ [[alternative HTML version deleted]]

Hola a todos.Quiero saber si existe una forma mas apropiada para hacer esto:tengo un dataframe de 40 variables y una de ellas es de fechas.lo que quiero es una tabla agregada por suma y como criterio de agrupación esta variable de fecha.en sql sería algo así: select fecha, sum(v1), sum(v2)..., sum(v39)from tablagroup by fecha; mi problema es que las vn pueden ser de dimensión cambiante, es decir,
