Hi R-listers, I am trying to make a trellis boxplot with the HSuccess (y-axis) in each Rayos (beach sections) (x-axis), for each Aeventexhumed (A, B, C) - nesting event. I am not able to do so and keep receiving: Error in eval(expr, envir, enclos) : object 'Rayos' not found Please advise, Jean require(plyr) resp <- read.csv("ABC Arribada R File Dec 12 Jean Jang.c...

Hi R - listers, I am receiving an error. Does anyone know what this means? J ggplot(subset(foo, Rayos != "Rayos.NA"), aes(x=HTL, y=DevelopIndex, colour=TotalEggs)) +geom_point() +geom_jitter() + facet_grid(Aeventexhumed ~ Rayos) + geom_smooth(method="lm", fill=NA) + ylim(c(0, 7)) Error in +geom_smooth(method = "lm", fill = NA) : invalid argument to unary operato...

Hi R-listers, I am trying to compare sections of the beach separated from the HTL to the Veg (east to west), separated into indices (-5 to 30m), HTLIndex. Cross parallel (north to south) are major beach sections (Rayos 1, 2, 3, 4 and MNB). I am thinking to do an ANOVA for each independent rectangle of beach (not exactly but will be treated as). The HTL from (0-5m) in Rayo 1 is one rectangle of beach; (0-5m) in Rayo 2 is another... etc. I was considering an 2-way anova with interactions - see below. But this does...

Hi All, I am wondering if anyone can tell me what the warning message below the model means? J add1(DTA.glm,~ Aeventexhumed + Veg + Berm + HTL + Estuary + Rayos) Single term additions Model: cbind(MaxHatch, TotalEggs - MaxHatch) ~ Aeventexhumed + Veg + Berm + HTL Df Deviance AIC <none> 488.86 4232.9 Estuary 1 454.96 4201.0 Rayos 3 258.80 4008.9 Warning messages: 1: In model.matrix.default(Terms, m, contrasts.arg = objec...

...ows up on the graph as well. > scatterplot (Shells/TotalEggs ~ Sector, data = data.to.analyze) [1] "86" 2) Also how do you change the Y axis title? I don't want it to read Shells/TotalEggs, instead I would like it to read Average Hatching Rate (%). 3) What does this error mean? Rayos if composed of section 1, 2, 3, 4 and 5 > scatterplot (Shells/TotalEggs ~ Rayos, data = data.to.analyze) Error in plot.window(...) : need finite 'xlim' values In addition: Warning messages: 1: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by coercion 2: In min(x) : no non-mis...

...r the AIC, how do I interpret it is worth it to include another variable in the model? How do I know when to stop? Definitions of Variables: HTL - distance to high tide line (continuous) Veg - distance to vegetation Aeventexhumed - Event of exhumation Sector - number measurements along the beach Rayos - major sections of beach (grouped sectors) TotalEggs - nest egg density Example of how all models were created: Model2.glm <- glm(cbind(Shells, TotalEggs-Shells) ~ Aeventexhumed, data=data.to.analyze, family=binomial) Model7.glm <- glm(cbind(Shells, TotalEggs-Shells) ~ HTL:Veg, family = bi...

Hola, Daniel: Quizá deberías ser más explícito porque de la información que suministras yo solo te puedo decir que no veo la relación entre los 3 tipos de algoritmos que nombras: - un análisis de componentes principales puede ser una fase previa de los otros dos - hacer un cluster es un tipo de aprendizaje no supervisado, mientras que un clasificador normalmente es utilizado en aprendizaje

Hola de nuevo a todos, me gustaría pediros disculpas por los correos que he enviado. La razón de enviarlos es que pensaba que era también un foro en el que podía plantear cuestiones estadísticas, no solo sobre R en concreto. Siempre es importante aprender algo de todo lo que haces, así que lo que me llevo es el conocimiento de que aquí solo puedo plantear cuestiones de implementación en R, y

I am trying to create a frequency distribution and I am a bit confused.
