Hola comunidad, tengo el siguiente problema con la funcion stat_density2d (estimacion de densidad 2d.) del paquete ggplot2 stat_density2d (mapping = NULL, data = NULL, geom = "density2d", position = "identity", na.rm = FALSE, contour = TRUE, n = 100, ...) de esta función requiero ver el cálculo númerico de la estimación de la densidad, cuento co...

Hello, I'd be very grateful for help with some ggplot2's stat_density2d issues. First issue is with data limits. xlim() and ylim() doesn't seem to work; instead, estimates (and plotting) seems to be constrained to range(x), range(y) no matter what i do. The documentation says i can pass in kde2d's parameters to ... but pussing kde2d's "lims" para...

...datos. Por lo que veo usa la función de la librería MASS kde2d, para ver que hace esta escribe kde2d en la consola. Espero te sirva.

Hi all, I have been looking for means of add a contour around some points in a scatterplot as a means of representing the center of density for of the data. I'm imagining something like a 95% confidence estimate drawn around the data. So far I have found some code for drawing polygons around the data. These look nice, but in some cases the polygons are strongly influenced by outlying points.

Hola: Estoy intentando generar un mapa de calor que muestre, dadas unas coordenadas geográficas determinadas, el ?calor? (cuanto mas alto el valor de esta variable mas rojo y cuanto mas bajo mas azul) de una determinada variable. Es decir con unos datos como estos: x y z -3,716575 40,41743 3.169 -3,710735

Let me start by introducing myself as a biologist with only a little knowledge about programming in matlab and R. In the past I have succesfully created my figures in matlab using the hist3d command, but I have not access to matlab right now and would like to switch to R. I have used the plot command to create a figure of my data and it does almost what I want it to do. My data matrix looks like
