Hi All, I would like to extend the standard biplot of Grabriel (1971), which is done by the R function biplot(). Rather than just showing the variables as vectors (with arrows at end point), I would like to show them as line segments, where the segment runs from minimum value of the variable to its maximum. In other words, I would like to produce a plot similar to that shown in Figure 1 of Gabriel and Odoroff (1990), rather than the classical biplot shown in Figure 2 of the same paper. Has anyone generated biplots similar to Figure 1 of Gabriel and Odoroff? Any help is greatly appreciated. Best, Ravi. ---------------------------------------------------------------------------- ------- Ravi Varadhan, Ph.D. Assistant Professor, The Center on Aging and Health Division of Geriatric Medicine and Gerontology Johns Hopkins University Ph: (410) 502-2619 Fax: (410) 614-9625 Email: rvaradhan@jhmi.edu Webpage: http://www.jhsph.edu/agingandhealth/People/Faculty/Varadhan.html ---------------------------------------------------------------------------- -------- [[alternative HTML version deleted]]
