Which of the following package is implemented by lattice plotting system?

grDevices
grid
graphics
all of the mentioned

The correct answer is: D. all of the mentioned

The lattice plotting system is implemented by the packages lattice, grid, and grDevices.

The lattice package provides a powerful and flexible framework for creating publication-quality graphics. It is based on the idea of arranging data into a grid, and then using a variety of graphical elements to represent the data. The grid package provides the underlying infrastructure for the lattice package, and it also provides a number of useful functions for creating and manipulating graphics. The grDevices package provides a number of functions for working with graphics devices, such as the screen, a printer, or a file.

Here is an example of a plot created using the lattice package:

library(lattice)
data(cars)
plot(cars, y ~ speed)

This plot shows the relationship between the speed of a car and the distance it can travel in a quarter mile. The points are colored by the type of car (sedan, sports car, or luxury car).

The lattice package provides a number of features that make it a powerful tool for creating graphics. These features include:

  • The ability to arrange data into a grid
  • The ability to use a variety of graphical elements to represent the data
  • The ability to create publication-quality graphics
  • The ability to save graphics to files
  • The ability to export graphics to other formats

The grid package provides a number of features that make it a powerful tool for creating and manipulating graphics. These features include:

  • The ability to create and manipulate graphics objects
  • The ability to add and remove graphical elements
  • The ability to change the properties of graphical elements
  • The ability to save graphics to files
  • The ability to export graphics to other formats

The grDevices package provides a number of features that make it a powerful tool for working with graphics devices. These features include:

  • The ability to open and close graphics devices
  • The ability to set the properties of graphics devices
  • The ability to save graphics to graphics devices
  • The ability to export graphics to other formats
