If you later want to use the default versions of sd and var, you can detach the circular package by calling detach("package:circular").īuilding the rose diagram is a two-step process. Loading the circular package warns you that the default functions sd and var are masked, being replace with those from the package. The circular package makes constructing rose diagrams simple. Rose diagrams solve both of these problems by displaying the frequency distribution radially. More important, it fails to convey that the scale wraps around: 10° and 350° are numerically very different than 10° and 30°, but their angular differences are identical. A standard histogram does a poor job of this, partly because it doesn’t show directions as on compass. When we collect directional data, such as paleocurrent or wind directions, we need a way to show their frequency distribution.
