The “hist” Function in R

• Package: Base R (no specific package required)

• Purpose: Creates histograms of a numeric vector.

• General Class: Data Visualization

• Required Argument(s):

• x: A numeric vector.

• Notable Optional Arguments:

• breaks: A specification of the breakpoints (bins) for the histogram. This can be an integer specifying the number of breaks or a numeric vector specifying the breakpoints.

• main: A main title for the histogram.

• xlab: A label for the x-axis.

• ylab: A label for the y-axis.

• col: The color of the bars.

• border: The color of the border around the bars.

• freq: A logical value indicating whether the histogram should be based on frequencies (TRUE) or densities (FALSE). The default is TRUE.

• Example:

• # Example vector
  data <- c(2, 4, 6, 8, 10, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20)
  
  # Create a histogram
  hist(data, breaks = 5, main = "Histogram Example", xlab = "Values", col = "blue", border = "black")

• In this example, the hist function is used to create a histogram of the numeric vector data with 5 bins. The main title, x-axis label, color of bars, and border color are specified as additional arguments. The resulting histogram is then plotted.
