# Compute the value of CDF over Wilcoxon Rank Sum Distribution in R Programming – pwilcox() Function

`pwilcox()` function in R Language is used to compute the value of Cumulative Density Function(CDF) for Wilcoxonrank Sum Statistic Distribution over a sequence of Numeric Values.

Syntax: pwilcox(x, m, n)

Parameters:
x: Numeric Vector
m: Larger sample size
n: Smaller sample size

Example 1:

 `# R Program to compute the value of ` `# CDF over Wilcoxonrank Sum Distribution ` ` `  `# Creating a sequence of x-values ` `x <``-` `seq(``1``, ``10``, by ``=` `1``) ` ` `  `# Calling pwilcox() Function ` `y <``-` `pwilcox(x, m ``=` `10``, n ``=` `5``) ` `y `

Output:

Example 2:

 `# R Program to compute the value of ` `# CDF over Wilcoxonrank Sum Distribution ` ` `  `# Creating a sequence of x-values ` `x <``-` `seq(``1``, ``50``, by ``=` `1``) ` ` `  `# Calling pwilcox() Function ` `y <``-` `pwilcox(x, m ``=` `40``, n ``=` `20``) ` ` `  `# Plot a graph ` `plot(y) `
