scatterplot.ggobi {Rggobi}R Documentation

Creates a ggobi display containing a single scatterplot

Description

This adds a new display window to the specified ggobi instance which contains a scatterplot of the two variables

Usage

scatterplot.ggobi(x, y, .data=1, .gobi=getDefaultGGobi())

Arguments

x,y identifiers for the two variables to be displayed in the scatterplot. These should be given by name (as returned by dimnames.ggobiDataset, etc.). Alternatively, they can be given by index (starting at $1$). As with all ggobi plots, the variables must be in the same dataset.
.data the identifier for the dataset within the ggobi instance in which the x and y identifiers are to be resolved. This can be an integer giving the index of the desired dataset (starting at $1$), the name of the dataset (as returned by names.ggobiDataset, or, preferrably, an object of class ggobiDataset). If the last of these is used, the .ggobi argument is not used.
.gobi the identifier for the ggobi instance, either an integer giving it by index or an object of class ggobi.

Value

An object of class ggobiDisplay. This is an opaque type whose contents are to be interpreted by C code and other S functions only.

Examples

  g <- ggobi(system.file("data", "flea.xml", package="Rggobi"), args="-noinit")
  g$scatterplot("tars1", "tars2", .data = g[[1]])

    # Add a second dataset and then create a new scatterplot.
  g$setData(system.file("data", "sat.xml", package="Rggobi"), add = TRUE)
  g$scatterplot("SAT", "RATIO", .data = g[[2]]) 

   # The minimalist and unreadable invocation
  scatterplot.ggobi(c(1, 2))
