Compute the value of Quantile Function over F Distribution in R Programming – qf() Function

function in R Language is used to compute the value of quantile function over F distribution for a sequence of numeric values. It also creates a density plot of quantile function over F Distribution.**qf()**

Syntax:qf(x, df1, df2)

Parameters:x:Numeric Vectordf:Degree of Freedom

**Example 1:**

`# R Program to compute value of` `# Quantile Function over F Distribution` ` ` `# Creating a sequence of x-values` `x <` `-` `seq(` `0` `, ` `1` `, by ` `=` `0.2` `)` ` ` `# Calling qf() Function` `y <` `-` `qf(x, df1 ` `=` `2` `, df2 ` `=` `3` `)` `y` |

**Output:**

[1] 0.0000000 0.2405958 0.6085817 1.2630236 2.8860266 Inf

**Example 2:**

`# R Program to compute the value of` `# Quantile Function over F Distribution` ` ` `# Creating a sequence of x-values` `x <` `-` `seq(` `0` `, ` `1` `, by ` `=` `0.02` `)` ` ` `# Calling qf() Function` `y <` `-` `qf(x, df1 ` `=` `2` `, df2 ` `=` `3` `)` ` ` `# Plot a graph` `plot(y)` |
