R help - Nov 2004 - how can draw probability density plot?

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

I hope this is the direct operation you are looking for:

 curve(dnorm(x),from=-3,to=3)

Best regards,

Ales Ziberna
