view.order {pga} | R Documentation |
Visualizes the result from pga
; it's always used
together with view.bubble
. The order plot is very similar to
the so-called scree plot from principal component analysis. To select
variables, we look for a big gap in this plot and select the top few
variables. The bubble plot (see view.bubble
) will tell us
which variables are actually on the top.
view.order(obj, grid = F, filename=NULL, ...)
obj |
object created by pga . |
grid |
if TRUE , horizontal grid lines are added. |
filename |
name to store the output file. If NULL (default),
the plot will be made to the standard R graphic device. |
... |
other graphic parameters, such as ylim=c(0,1) . |
Please see pga-package for an introductory overview and examples.
