# Compute the Value of Cumulative Weibull Density in R Programming – pweibull() Function

Last Updated : 25 Jun, 2020

`pweibull()` function in R Language is used to compute the value of Cumulative Distribution Function for Weibull Distribution. It also plots a density graph for Cumulative Weibull Function.

Syntax: pweibull(x, shape)

Parameters:
x: Numeric Vector
shape: Shape Parameter

Example 1:

 `# R Program to compute ` `# Cumulative Weibull Density ` ` `  `# Creating a sequence of x-values ` `x <``-` `seq(``-``5``, ``15``, by ``=` `1``) ` ` `  `# Calling pweibull() Function ` `y <``-` `pweibull(x, shape ``=` `0.2``) ` `y `

Output:

``` [1] 0.0000000 0.0000000 0.0000000 0.0000000 0.0000000 0.0000000 0.6321206
