The "xyz_data" argument is actually a matrix with columns x, y, and z. However, the "polys" object is a list - and probably needs to remain so in order to define the coordinates of each polygon to be plotted on the projection. The above example uses a "perspective" projection I believe. The map.xyz function assumes a default of "stereographic". I hope this helps - thanks for your comment!Marc in the boxhttps://www.blogger.com/profile/00459761376667614040noreply@blogger.comtag:blogger.com,1999:blog-6424211413492597169.post-90469526312756887212012-02-27T14:26:40.701+01:002012-02-27T14:26:40.701+01:00Hi,

Basically I use NetCDF data a lot, and all the data I work on is array based. What I would like to do is some stereographic projections but haven't been able to work out how to do them in R. Your plots (and the ones for the MCA) look great and I would really like to be able to do similar!Alexnoreply@blogger.com
