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
