ggobi accessors {Rggobi} | R Documentation |
Most of the functions in this ggobi package act on a ggobi
instance. The $
operator allows one to treat these functions as
method calls on the instance, in the form of g$method
. This
allows one to explicitly indicate which ggobi instance is being used
and also to avoid typing the .ggobi
suffix for the different
functions.
"$.ggobi"(x, name)
x |
the ggobi instance in the form of an object of class ggobi . |
name |
the name of the function to be invoked, without the
.ggobi suffix. |
This creates a closure which ``remembers'' the
ggobi
instance g
and returns a function
which will call the function named textit{name}.ggobi
with that ggobi
object as the named argument
.gobi
.
This is then called directly and its return value
rarely stored for future computations.

$.ggobi
All functions that take a .gobi
argument
and are named *.ggobi
.
g <- ggobi(system.file("data", "flea.xml", package="Rggobi")) g$getDisplays() g$getDisplayCount() g$getDatasetReference(1) # g[1]
