Hi All, Can anyone point me a hint (package) how to draw a 3D plot using the first 3 components from PCA? Thanks a lot, FD
See ?ordiplot3d and ?ordirgl in package vegan. rda() in that package can be used to perform PCA, which can then be drawn in 3D using the rgl package or the scatterplot3d package, the former allowing dynamic rotation and zooming of the ordination configuration. HTH G
