Dear support,

I want to draw a probability density plot in R. For
example, I provide the mean and variance of a normal
distribution, then R can provide me the probability
density plot. Now I always generate random numbers of
normal distribution and calculate their dnorm(mu,
var), finally plot them. I am eager to know some
directly operation.

Thank you for your attention.

I am looking forward to hearing from you soon. 

 

Best regards,

Long Yu
