# Compute Randomly Drawn Chi Square Density in R Programming – rchisq() Function

`rchisq()` function in R Language is used to compute random chi square density for a set of values.

Syntax: rchisq(N, df)

Parameters:
N: Sample Size
df: Degree of Freedom

Example 1:

 `# R program to generate  ` `# random chi square density points ` ` `  `# Setting seed for ` `# random number generation ` `set``.seed(``1000``) ` ` `  `# Set sample size ` `N <``-` `20` ` `  `# Calling rchisq() Function ` `y <``-` `rchisq(N, df ``=` `10``) ` `y  `

Output:

```   7.208082 11.236799  3.780669  5.972266 12.174243 14.308333  3.886482

  4.546996 11.542960  9.683502  9.073933 11.120782  9.193626
```

Example 2:

 `# R program to generate  ` `# random chi square density points ` ` `  `# Setting seed for ` `# random number generation ` `set``.seed(``1000``) ` ` `  `# Set sample size ` `N <``-` `500` ` `  `# Calling rchisq() Function ` `y <``-` `rchisq(N, df ``=` `10``) ` ` `  `# Plotting graph ` `plot(y) `
