segments in 3d space
3 messages · Adrian Dusa, Spencer Graves, Uwe Ligges
Have you looked at the documentation on "persp", especially the function "trans3d" in the examples? Also, have you tried www.r-project.org -> search -> "R site search", searching for what you want? This "persp" -> "trans3d" was mentioned in another recent discussion on this list. hope this helps. spencer graves

Hi all, Is it possible to draw line segments in a 3d space plot? I'm interested to draw the errors from an observed value to the regression plane, for a textbook example in an Intro Stats handbook for multiple regression. I used the scatterplot3d package to draw the regression plane. Many thanks, Adrian ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Adrian Dusa (adi at roda.ro) Romanian Social Data Archive (www.roda.ro) 1, Schitu Magureanu Bd. 76625 Bucharest sector 5 Romania Tel./Fax: +40 (21) 312.66.18\ +40 (21) 312.02.10/ int.101 [[alternative HTML version deleted]]

An example on how to draw segments for residuals on a regression plane with scatterplot3d is shown in Section 4.2.2 (pp. 20-22) of Ligges, U. and M?chler, M. (2002): Scatterplot3d - an R Package for Visualizing Multivariate Data. Technical Report 22/2002.
