Estimados miembros de la lista. Estoy usando 2 funciones del paquete vcd y obtengo resultados que parecen discrepar entre ambas funciones. > dput(peces) c(26L, 63L, 1L, 21L, 20L, 50L, 0L, 104L, 19L, 0L, 8L, 32L, 0L, 24L, 5L, 2L, 0L, 36L, 0L, 5L, 27L, 1L, 13L, 24L, 15L, 25L, 23L, 5L, 37L, 26L, 29L, 14L, 15L) La función Ord_plot me dice que la mejor distribución para los datos es binomial negativa. Ord_plot(peces) La función distplot parece indi...

Hola a tod en s, Trabajo con datos de abundancia (número de individuos) por tallas (medidas al medio centímetro inferior) de diferentes especies de peces y mis datos base son el número medido de peces por talla. Necesitaría vuestra ayuda para transformar las distribuciones de frecuencias de talla a los datos brutos que las generaían. Es decir, pasar de algo como esto 8           1 8.5        3 9          5 10        7 10.5     4 11        2 1...

I am trying to draw maps for the world using: library(rworldmap) library(maptools) library(RColorBrewer) tmp2<- dput(head(pece,10)) structure(list(iso3 = c("AUS", "AUT", "BEL", "CAN", "CHE", "CHL", "CZE", "DEU", "DNK", "ESP"), eps_score = c(0.877343773841858, 2.68984365463257, 1.31406247615814, 1.98046875, 2.61666655540466,...

...amlss para este caso es "beta inflated" (Stasinopulos and Rigby 2007. Journal of Statistical Software 23(7)). El modelo que intento correr es: m1<-gamlss(Teleosteos ~ cs(LT_max)+random(Familia/Genero,lambda=T),family=BEINF, data = datos) donde LT_max es la talla máxima de especies de peces y la variable respuesta es la proporción del consumo de peces teleósteos de cada especie. El efecto aleatorio es anidado de géneros y familias taxonómicas de especies (género dentro de familia). El problema que tengo es que los gamlss no toman el efecto aleatorio como random(Familia/Genero) o (1|F...

Hola, buen día. Una consulta, no sé conozco en extenso todas las bondades de R, pero quería saber exactamente si hay algún paquete que permita realizar análisis ecológicos específicamente para comunidades marinas. Existen muchos índices, indicadores, estimadores en general en muchos programas que están a nivel de usuario, pero quería saber si todos estos pueden estar ya disponibles en R.

Amigos de la erre. He creado mi primer bucle con for para entrenar unos modelos con GAM. La respuesta es quasipoisson porque estoy trabajando con densidades de peces. Sin embargo, tengo un problema, no se muy bien como añadir el offset a la formula siguiente cuando creo el bucle. GAM.A1 <-gam ((DYO)~s(DMA,k=4)+ s(WOD,k=4)+s(CIN,k=4)+s(DRA,k=4)+s(DBR,k=4) +offset(log(ARE)),family=quasipoisson(link = "log"),data=as.data.frame(cbind(DYO,Conjunto)))...

...evels) of a bird presence/absence (pres.f) on 14 artificial ponds (charca.f). The ponds are integrated in 4 greater spatial units (zepa). I have 11 explanatory variables, some of them are continuous (prof1,prof2,prof4,capac,perim_veget,div_veg,div_herp) and some are factors (ungul.f,ganado.f,turb.f,peces.f). Not all artificial ponds have been monitored in all seasons, so I have some missing values in the dependent variable. I have thought that the correct model should be, ignoring the spatial pseudorreplication: m1<-lmer(pres.f~ganado.f+ungul.f+turb.f+prof1+prof2+prof4+capac+perim_veget+pe...
