R Plot Parameters Guide
In R programming language, you can use the plot() function to create graphs and adjust their styles by setting parameters. Here are some common plot parameters and their settings:
- X: specifies the x-axis coordinate value of the data to be plotted.
- y: designated y-axis coordinate value for the data to be plotted.
- Specify the type of graph to be plotted, such as “p” for scatter plot, “l” for line plot, or “b” for both line and scatter plot.
- Main: Set the title of the graphic.
- xlab and ylab: labels for the x-axis and y-axis.
- Set the range of the x-axis and y-axis with xlim and ylim.
- Set the color of the point or line.
- pch: specify the shape of the points.
- lty: specify the line type.
- cex: Adjust the size of the points.
- legend: include a caption.
For example, here is a simple example demonstrating how to use the plot() function and parameters to draw a basic scatter plot.
x <- c(1, 2, 3, 4, 5)
y <- c(2, 4, 6, 8, 10)
plot(x, y, type = "p", col = "red", pch = 16, main = "Scatter Plot", xlab = "X Axis", ylab = "Y Axis")
By adjusting various parameters, customized graphics can be created to meet specific requirements. For more parameter settings, please refer to the official documentation of R language or use help(plot) for detailed instructions.
