Set the tour projection from a GGobi tour.
ggobi_display_set_tour_projection(gd, value)
GGobiDisplay object running tour
tour projection
If you know the projection you would like to see in the tour, you can use this function to set it. The example illustrates setting the projection to show the first two principle components.
# NOT RUN {
if (interactive()) {
g <- ggobi(mtcars)
d <- displays(g)[[1]]
}
# }
# NOT RUN {
pmode(d) <- "2D Tour"
variables(d) <- list(X=names(mtcars))
ggobi_display_get_tour_projection(d)
pc <- princomp(as.matrix(mtcars))$loadings[,1:2]
ggobi_display_set_tour_projection(d, pc)
pc <- princomp(as.matrix(mtcars), cor=T)$loadings
ggobi_display_set_tour_projection(d, pc)[,1:2]
# }
