Point out the correct statement.

Vector formats are good for line drawings and plots with solid colors using a modest number of points
Vector formats are good for plots with a large number of points, natural scenes or web based plots
The default graphics device is always the screen device
All of the mentioned

The correct answer is D. All of the mentioned.

Vector formats are good for line drawings and plots with solid colors using a modest number of points. This is because vector formats store the data for a drawing as a set of instructions, rather than as a bitmap of the image. This means that vector formats can be scaled to any size without losing quality.

Vector formats are also good for plots with a large number of points, natural scenes or web based plots. This is because vector formats can represent complex shapes and images with a relatively small amount of data.

The default graphics device is always the screen device. This means that when you create a plot in R, it will be displayed on your screen by default.

Here is a more detailed explanation of each option:

  • Option A: Vector formats are good for line drawings and plots with solid colors using a modest number of points. This is because vector formats store the data for a drawing as a set of instructions, rather than as a bitmap of the image. This means that vector formats can be scaled to any size without losing quality. For example, if you have a vector drawing of a line, you can scale it up to be as large as you want, and the line will still be smooth and clear.
  • Option B: Vector formats are good for plots with a large number of points, natural scenes or web based plots. This is because vector formats can represent complex shapes and images with a relatively small amount of data. For example, if you have a vector drawing of a map, you can zoom in and out of the map without losing any detail.
  • Option C: The default graphics device is always the screen device. This means that when you create a plot in R, it will be displayed on your screen by default. You can change the default graphics device to another device, such as a printer or a file, but this is not necessary for most purposes.
  • Option D: All of the mentioned. This is the correct answer, as all of the options are true.
