Plot a circle in polar coordinates
Webb2 apr. 2024 · It returns the Cartesian coordinates ‘xv’, ‘yv’, and ‘zv’ that are vectors because φ is the vector ‘phiv’. Those are then transformed into the longitude coordinates ‘lv’ , and corresponding latitude coordinates ‘bv’ , in the ‘ct2sp’ call immediately after that, both of them being vectors as well, because their arguments are vectors. Webbför 2 dagar sedan · The polar dendrogram should still lie in a 2D plane in 3D space. The only difference is that it is a polar dendrogram. For 2D images, coord_polar in ggplot2 is used to create polar dendrogram. But I do not know how to do this in 3D. P.S. After converting to 3D polar dendrograms, I want to add 3D meshes at specified position …
