R equivalent of Matlab trisurf()

I have three vectors x, y, U that I would like to plot as a surface. I can do this in Matlab using functions delaunay() and trisurf(). However, I would like to do the same in R but can't find something similar.

Any help appreciated.

You can do trisurf with Plotly's open-source R client. R code here:

See the geometry package for delaunayn and surf.tri, and these can be plotted with rgl.triangles from rgl.

I used this recently here https://gis.stackexchange.com/questions/90635/what-programs-would-allow-for-the-mapping-of-a-geoid-in-3d/90763#90763
