For this tutorial I will simulate 100000 directions using the wrapped normal function (rwrpnorm) from the CircStats package. The dataĪs I mentioned, my data was related to seal swimming directions, gathered from satellite tags. In fact, if you look through the ggplot2 call, it is basically a histogram until the last couple of lines, where it is wrapped into a wind rose. In reality it doesn't matter too much what you want to plot, and these sorts of plots are more generally used for wind direction illustrations. In my article I wanted a graphic which illustrated the preferred outward post-moult migration direction of adult female southern elephant seals from Marion Island. Essentially, I have created a histogram for orientation of these cells and now I want to plot that data on a circular graph to show 'x' cell type is more oriented towards something than 'y' cell type.

As before, I relied heavily on Stack Exchange and many other sites for figuring out how to get my plot looking the way I needed it to, and so this is my attempt to contribute back to the broader community. I'm very inexperienced with R (or any type of coding), but I'm trying to make a rose plot using the package circular for directional data from cells. Y <- rose.diag(x, bins=18, prop=1.5, shrink=1.This is another post regarding some plots that I needed to make for a publication. Y <- rose.diag(x, bins=18) # Points fall out of bounds.
X <- rvonmises(n=50, mu=circular(0), kappa=5, control.circular=list(zero=pi/4)) # Generate von Mises data and create several rose diagrams. Rose.diag(x, bins = 18, main = 'Uniform Data') # Some optional parameters may be needed to optimize plots. # Generate uniform data and create several rose diagrams. Since version 0.3-9 the intervals are on the form [a,b). The length of the radii can be controlled by varying the parameter prop. This ensures that the area of the sector is proportional to the group frequency. The radii of the sectors are by default equal to the square root of the relative frequencies of observations in each group. The circumference of the circle is split into groups, the number of groups specified by bins.
