Details

This function allows you to create a new display from a GGobiData object. You will need to specify the type of display you want ("Scatterplot Display", "Scatterplot Matrix" and "Parallel Coordinates Display" are the most common), and which variables the plot should be intialised with. Specifying more than two variables only makes sense for scatterplot matrices and pcps.

Many of the plots used in GGobi (eg. the tours and densities plots) are special modes of the scatterplot display. You will need to create a new scatterplot display, change the projection mode to what you want, and then set the variables. Hopefully this will be improved in a future version of rggobi.

# NOT RUN {
if (interactive()) {
g <- ggobi(mtcars)
display(g[1])
display(g[1], vars=list(X=4, Y=5))
display(g[1], vars=list(X="drat", Y="hp"))
display(g[1], "Parallel Coordinates Display")
}
# }
# NOT RUN {
display(g[1], "2D Tour")
display(g[1], "2x1D Tour", list(X=c(1,2,3), Y=c(4,5,6)))
display(g[1], "Scatterplot Matrix")
# }
