Hola He estado tratando varias formas de colocar el subíndice para los grados de libertad del F test y la expresión adj; y sencillamente no funciona. legend("topright",legend=c(expression('r[adj]=0.40'),expression('F[3,23]=15.43'),expression('P < 0.001')),col=black, bty='n',cex=0.9) Luego al tratar de colocar las cusriva utilizando par(font=3)

Estimados En este modelo no puedo hacer el plot(svmfit,df11 ) #AQUI NO TRABAJA Le adjunto Excel library(readxl) df11 attach(df11) df11$fallecido=factor(df11$fallecido) # Selección de una submuestra del 70% de los datos set.seed(101) tamano.total <- nrow(df11) tamano.entreno <- round(tamano.total*0.7) datos.indices <- sample(1:tamano.total , size=tamano.entreno) datos.entreno <-

Hola, El mensaje es claro: el modelo svmfit no existe, tú has llamado al ajuste ?modelo?. De todas formas, aparte de eso tendrías que especificar qué dimensiones (variables predictivas) quieres representar. Si miras en la ayuda de ?plot.svm lo tienes explicado. Esto sí funcionaría: plot(modelo,df11, LDH ~ INL ) Gracias por proporcionar el código y los datos para poder reproducir el error. Un

Hola una pregunta: ¿Alguien ha trabajado con shinyTable? Mi pregunta es si se puede controlar el tamano de una tabla que se muestra por pantalla El tema es el siguiente: Con esta parte de codigo: output$tbl <- renderHtable({ if (is.null(input$tbl)){ #fill table with 0 tbl <-

Dear R users, Recent changes to the MuMIn package now means that the model averaging command (model.avg) no longer returns confidence intervals, but instead returns zvalues and corresponding pvalues for fixed effects included in models. Previously I have used this package for model selection/averaging following Greuber et al (2011) where it suggests that one should use confidence intervals from

Hola! Para simular matrices de datos normales multivariados con la sentencia rmvnorm (dentro del paquete mvtnorm) se necesita, entre otras cosas, el número de vectores a simular, el vector de parámetros-medias correspondiente a cada variable y su respectiva matriz de Varianza-Covarianza. En este último punto, tengo problemas. En lugar de ingresar una matriz sigma creada por mi, necesito simular

Dear R users, I am using lmer combined with AIC model selection and averaging (in the MuMIn package) to try and assess how isotope values (which indicate diet) vary within a population of animals. I have multiple measures from individuals (variable 'Tattoo') and multiple individuals within social groups within 4 locations (A, B, C ,D) crucially I am interested if there are

Hola, Tengo la base de datos de un censo agropecuario el cual está en formato de SPSS, cuando cuando ejecuto el comando para introducirlo a R, despues de permanecer lento R, aparece esto: Error: cannot allocate vector of size 1.6 Mb Hasta aquí llega y no introduce ninguna observación. Mi pregunta es si existe alguna solución, talvez aumentar la memoria de R?? Imagino que como ustedes han

Is there any documentation about replacement and extraction functions in R, these fuenctions don't work as in S. Example with funtion factor.names (of S+ 4.5r2) > fnombres <- list(tratamiento=LETTERS[1:4], veneno=c("I","II","III")) > veneno.diseno <- data.frame( + factor(rep(c(1,2,3,4), rep(12,4))), + factor(rep(rep(c(1,2,3), rep(4,3)),4)) + ) >

Hi all, I'm hoping I might be able to get some help with some issues specifying priors for MCMCglmm. I'm trying to fit a gaussian glmm using MCMCglmm to a data set with two (correlated) response variables. The response variables are both logit-transformed proportions (there are a few reasons why I've chosen these with gaussian error over binomal glmm, which I won't go into).

Hi, I am an R newbie and one thing I am having trouble with binding variables that I have created within one data frame into a new data frame when using na.omit(). To illustrate this problem I will give the example I am working on and the approah I have been using:- data.frame1<-filepath.... attach(data.frame1) #create a new variable using a function new.variable<-rep(1,length(weight3))

Hi, This patch adds R600/SI disassembly text to compiled object files, when a code dump is requested, to assist debugging in Mesa clients. Here's an example of the output in a Mesa client with a corresponding patch and RADEON_DUMP_SHADERS set: Shader Disassembly: S_WQM_B64 EXEC, EXEC ; BEFE0A7E S_MOV_B32 M0, SGPR6 ; BEFC0306

Hi all, I have been bumbling around with r for years now and still havent come up with a solution for plotting reliable graphs of relationships from a linear regression. Here is an example illustrating my problem 1.I do a linear regression as follows summary(lm(n.day13~n.day1+ffemale.yell+fmale.yell+fmale.chroma,data=surv)) which gives some nice sig. results Coefficients:

Hello, In a study exploring transgenerational transmission of anxiety disorder we investigate whether infants react to experimentally induced mood changes of their mothers. We measured the time that an infant needed to cross a cliff (=crossing time) depending on whether his mother had previously undergone a mood induction (treatment) or not (control). The treatment is thus a

Hi, I've encountered a problem invoking LLVM-generated x86_64 code on Windows from MSVC-compiled code. There seems to be disagreement between the two compilers over the calling convention for passing a 12 or 16 byte structure by value. e.g. struct aggregate { int a; int b; int c; int d; }; int test(aggregate byVal) { ... } LLVM chooses to pass byVal with a and b packed into rcx

Hi, I would like to (if possible) set the default width and height for graphs at the start of each session and have each new graphic device overwrite the previous one. I only know how to do this using windows(width=,height=...) which opens up a new plotting device every time, so I end up with lots of graphs all over the place until I get the one I want! Thanks in advance, Simon Simon Pickett
