The “rgamma” Function in R

• Package: Base R (no specific package required)

• Purpose: Generates random numbers from a gamma distribution.

• General Class: Random Number Generation

• Required Argument(s):

• n: The number of random values to generate.

• shape: The shape parameter of the gamma distribution.

• Notable Optional Arguments:

• rate: The rate parameter of the gamma distribution.

• scale: An alternative to the rate parameter, specifying the scale of the gamma distribution (scale = 1/rate).

• Example:

• # Generate 100 random values from a gamma distribution with shape 2 and rate 0.5
  random_values <- rgamma(n = 100, shape = 2, rate = 0.5)
  print(random_values)

• In this example, the rgamma function is used to generate 100 random values from a gamma distribution with a shape parameter of 2 and a rate parameter of 0.5. The generated values are then printed to the console.
