The “plot” Function in R

• Package: Base R (no specific package required)

• Purpose: Creates various types of plots for visualizing data.

• General Class: Data Visualization

• Required Argument(s):

• x: The x-axis variable.

• y: The y-axis variable.

• Notable Optional Arguments:

• type: A character string specifying the type of plot. Options include “p” for points, “l” for lines, “b” for both, “c” for empty points with lines, “s” for stair steps, and more.

• main: A main title for the plot.

• xlab: A label for the x-axis.

• ylab: A label for the y-axis.

• col: The color of the plotted elements.

• pch: The plotting symbol (integer or single character) for points.

• lty: The line type.

• xlim and ylim: Limits for the x and y axes.

• ...: Additional graphical parameters.

• Example:

• # Example vectors
  x <- c(1, 2, 3, 4, 5)
  y <- c(2, 4, 6, 8, 10)
  
  # Create a scatter plot
  plot(x, y, type = "p", main = "Scatter Plot Example", xlab = "X-axis", ylab = "Y-axis", col = "blue", pch = 16)

• In this example, the plot function is used to create a scatter plot of the vectors x and y. The type of plot, main title, axis labels, color of points, and plotting symbol are specified as additional arguments. The resulting scatter plot is then displayed.
