Compute the gamma value of a Non-negative Numeric Vector in R Programming – gamma() Function
gamma()
function in R Language is used to compute the gamma value of a numeric vector using the gamma function.
Gamma function is basically,
gamma(x) = factorial(x - 1)
Syntax: gamma(x)
Parameters:
x: Non-negative Numeric Vector
Example 1:
gamma( 2 )
gamma( 3 )
gamma( 5 )
|
Output:
[1] 1
[1] 2
[1] 24
Example 2:
x1 < - c( 2 , 3 , 5 )
x2 < - c( 6 , 7 , 8 )
x3 < - c( - 1 , - 2 , - 3 )
gamma(x1)
gamma(x2)
gamma(x3)
|
Output:
[1] 1 2 24
[1] 120 720 5040
[1] NaN NaN NaN
Warning message:
In gamma(x3) : NaNs produced
Here, in the above code, the NaN is produced for a Negative numeric vector.
