ggplot2 - 3D polar plot in R -


i have plotted polar coordinates data using ggplot2.

my dataset in format:

 time    lat    long   act  18:00  21.05   70.00  feed  18:45  21.00   75.00  walk  19:00  21.09   77.00  walk  19:05  24.98   77.09  rest

code :

library(ggplot2) plot.new()  ggplot(aes(x = lat, y = long, colour = act), data = file) +  geom_point()  ggplot(aes(x= lat, y = long , colour = act), data = file) +  geom_point() +  coord_polar(theta = "y")

this polar coordinate plot get: here

this plot having latitude , longitude. add 1 more dimension "time". how can ?. how can make 2d polar plot in 3d polar plot ?

you try scale size of points value of variable "time". unfortunately example not reproducible, along these lines work:

ggplot(aes(x= latitude, y = longitude , colour = activity, size=time), data = data) + geom_point(shape=21) + coord_polar(theta = "y") + scale_size_area(max_size=10)

below can see reproducible example, based on data used in "the r graphics cookbook" winston chang (o'reilly 2013).

in case, dot size represents temperature, color refers wind speed category, direction of wind plotted in polar coordinates , radius average value of wind.

library(gcookbook) library(ggplot2) p <- ggplot(wind, aes(x=winddir, y=windavg, size=temp, fill=speedcat)) +      coord_polar() + geom_point(shape=21)+scale_size_area(max_size=10) +      scale_x_continuous(limits=c(0,360),breaks=seq(0,360,by=45))

this output: enter image description here

hope helps.
