ggperiodic

ggperiodic is an attempt to solve the issue of plotting periodic data inggplot2. It automatically augments your data to wrap it around to anyarbitrary domain.

Installation

You can install the latest version from CRAN with

install.packages("ggperiodic")

Or you can install the development version fromGitHub with:

# install.packages("devtools")devtools::install_github("eliocamp/ggperiodic")

Example

Let’s create some artificial data with periodic domain

x<- seq(0,360-10,by=10)*pi/180y<- seq(-90,90,by=10)*pi/180Z<- expand.grid(x=x,y=y)Z$z<- with(Z,1.2*sin(x)*0.4*sin(y*2)-0.5*cos(2*x)*0.5*sin(3*y)+0.2*sin(4*x)*0.45*cos(2*x))Z$x<-Z$x*180/piZ$y<-Z$y*180/pi

If you try to plot it, you’ll notice problems at the limits

library(ggplot2)ggplot(Z, aes(x,y,z=z,color=..level..))+  geom_contour()+  coord_polar()

With ggperiodic you can define the periodic dimensions and ggplot2 doesthe rest.
