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.
