similar to: comportamiento de data.table al hacer calculos por grupos

Muchas gracias Freddy y Carlos ... estuve intentando con .() y con list(), para calcular la media y el error estandar al mismo tiempo en dos columnas, pero me arrojaba un error que no supe interpretar. Ahora ya funciona como sugiere Carlos. Muchas gracias de nuevo. Saludos, Eric. On 14/05/15 19:28, Carlos Ortega wrote: > Hola, > > La forma de hacerlo con data.table es esta: >

Bueno, una pequeña vuelta de tuerca más usando ggplot.. Aunque no quedó tan limpio como el de Carlos (gran resolucion) tambien te sirve. Un saludo library(ggplot2) dec.df <- mat[mat$sol=="dec",] lim.df <- mat[mat$sol=="lim",] dol.df <- mat[mat$sol=="dol",] dec.dr<-qplot(dia,V5,sol,data=dec.df,color=con2,geom=c("line"),facets=.~sol) lim.dr

Estimada comunidad, tengo el siguiente problema: Un data.frame con muchas filas de las que debo eliminar aquellas que cumplen varios criterios al mismo tiempo. Por ejemplo este data.frame: sol con dia NCar NIns isom area rep tipo 1 con 0.001 1 160s 0 s 6.083543e-01 1 2 con 0.001 1 161c 1 c 1.391274e-03 1 <NA> 3 con 0.001 1 161c 1 c

Estimados, tengo un grafico al que debo anexar la leyenda en el costado derecho. Mi problema es que el titulo de la leyenda debe decir "Concentration (mM)" el que es muy largo y la ultima M sale cortada. No puedo abreviar la palabra porque justamente me rechazaron el grafico por que estaba abreviada esa palabra. Aqui pego el codigo con el que se hacen los graficos y anexo un archivo

Hola, Aunque un poco más elaborado, el resultado me parece más limpio (adjunto gráfico). He utilizado gran parte del código de "pepecb". Por otro lado (Neo) es recomendable que cuando incluyas una duda en la lista des también referencia de su sesión (comando de R: sesionInfo). La función que usas "xYplot()" es del paquete "Hmisc" y aunque está basada en el paquete

John: I wanted to add that I have no problem logging into the samba server with a domain account, as long as it's not through KDE. The first time error's out complaining about DCOPServer and not being able to write to the home directory....don't know if this is relevant. My experience is very limited on Unix and Samba. Please forgive me if the answer is right in front of me.

Hi [macOSX 10.4.6; R-2.3.0] I have encountered a difference in behaviour between R-2.2.1 and R-2.3.0 when performing a linear model. Transcript follows for R-2.3.0 (R-2.2.1 worked as expected).

Dear List, i am trying to produce a 3d plot using wireframe using the code: wireframe(Residuals_FD ~ Elevation * Temperature, data = data2, scales = list(arrows = FALSE), drape = TRUE, colorkey = TRUE) As you can see when the code (using the data below) is run the plot area is set-up correctly but the actual surface is missing? Any help would be greatly appreciated. Chris #data Elevation

I am calculating the mean of each column grouped by the variable 'id'. I do this using aggregate, data.table, and plyr. My aggregate results do not match the other two, and I am trying to figure out what is incorrect with my syntax. Any suggestions? Thanks. Here is the data. myData <- structure(list(var1 = c(31.59, 32.21, 31.78, 31.34, 31.61, 31.61, 30.59, 30.84, 30.98, 30.79, 30.79,

R Help - I'm trying to run a correlation matrix with a covariate of "age" and will at some point will also want to covary other variables concurrently.

How can I accomplish this? library(psych) > set.cor(y =

Estimada comunidad, voy a describir lo que necesito hacer y no he encontrado como, pues no se si hay funciones en R para esto. Tengo la siguiente tabla de doble entrada que obtuve con la funcion CAST: sol 1 2 3 4 5 1 con 0.00259587 NaN NaN 0.001905260 NaN 2 dec NaN 0.002719438 NaN 0.002339808 0.002970884 3

Hola, ¿qué tal? Creo que las funciones melt (particularmente) y cast del paquete reshape te pueden ayudar. Con melt podrías transformar tu df en algo con el aspecto sol col valor con 1 0.000... con 2 NaN ... Un saludo, Carlos J.

Gracias Olivier por tu sugerencia ... uso "cast" porque me permite hacer facilmente algunas operaciones con los datos antes de graficarlos, por ejemplo, calcular el promedio de los datos que cumplan un conjunto de condiciones. Por ejemplo, graficar el promedio de la variable "are" que cumplan: sol=="dol" , dia==1, con==5 y asi ... tambien lo hacia de otra forma q
