# Compute the value of Quantile Function over Wilcoxon Signedrank Distribution in R Programming – qsignrank() Function

Last Updated : 25 Jun, 2020

`qsignrank()` function in R Language is used to compute the value of Quantile Function(QF) over Wilcoxon Signedrank Statistic Distribution for a sequence of Numeric values.

Syntax: qsignrank(x, n)

Parameters:
x: Numeric Vector
n: Sample Size

Example 1:

 `# R Program to compute the value of ` `# QF over Wilcoxon Signedrank Distribution ` ` `  `# Creating a sequence of x-values ` `x <``-` `seq(``0``, ``1``, by ``=` `0.1``) ` ` `  `# Calling qsignrank() Function ` `y <``-` `qsignrank(x, n ``=` `10``) ` `y `

Output:

``` [1]  0 15 19 22 25 27 30 33 36 40 55
```

Example 2:

 `# R Program to compute the value of ` `# QF over Wilcoxon Signedrank Distribution ` ` `  `# Creating a sequence of x-values ` `x <``-` `seq(``0``, ``1``, by ``=` `0.02``) ` ` `  `# Calling qsignrank() Function ` `y <``-` `qsignrank(x, n ``=` `15``) ` ` `  `# Plot a graph ` `plot(y) `

Output:
