WebAgain, we need to create a vector of quantiles: x_plnorm <- seq (0, 10, by = 0.01) # Specify x-values for plnorm function. And then, we need to insert this vector into the plnorm command: y_plnorm <- plnorm ( x_plnorm) # Apply plnorm function. We can draw the cumulative distribution function as follows: plot ( y_plnorm) # Plot plnorm values. WebWith these functions, I can do some fun plotting. I create a sequence of values from -4 to 4, and then calculate both the standard normal PDF and the CDF of each of those values. I also generate 1000 random draws from the standard normal distribution. I then plot …
