  • Last Updated : 25 Jun, 2020

plogis() function in R Language is used to compute logistic cumulative density of the distribution. It also creates a plot of the density of the logistic cumulative distribution.

Syntax: plogis(vec)

Parameters:
vec: Vector of x-values for density

# R program to calculate 
# cumulative logistic density
  
# Create a vector of x-values
x <- seq(-1, 1, by = 0.1)
  
# Calling the plogis() function
y <- plogis(x)
