Parallax View

"The Parallax View" was a fun movie, especially for those with a conspiracy slant on the world. One might even see it as harbinger of "Robocop". Well, it turns out that there is at least one other take on scatterplot matrix. In the context of the authors' data, it makes some sense.

I tried it with the Triage database table, but am not so convinced it helps for the discrete data proposed. Have a look, and see what you think:

CREATE OR REPLACE FUNCTION "public"."pairs_graph" () RETURNS text AS
$BODY$
library(ggplot2)
library(GGally)
X11(display=':5');
events <- pg.spi.exec ("select period, event, amount, choice, guncontrol, outcome from public.events where candidate = 'Doe' ");
png('ggpairs_graph.png');
events$gcfactor <- as.factor(events$guncontrol)
p <- ggpairs(events, columns=c("period", "amount", "choice", "gcfactor"),
    diag=list(continuous="density",   discrete="bar"), axisLabels="show")
print(p)
dev.off();
print('done');
$BODY$
LANGUAGE 'plr'

And here's the graph:
