df()
function in R Language is used to compute the density of F Distribution over a sequence of numeric values. It also plots a density graph for F Distribution.
Syntax: df(x, df1, df2)
Parameters:
x: Numeric Vector
df: Degree of Freedom
Example 1:
x < - seq( 1 , 30 , by = 2 )
y < - df(x, df1 = 2 , df2 = 3 )
y
