Hello,

I am new to R and have two easy questions.

How can you plot multiple density functions in one graph?  I have  
five beta
densities that I would like to plot in one graph.  I understand how  
to plot
one beta density as a line:

plot (x,(dbeta(x,shape1=,shape2=,), type ="l")

?lines

Does the Pareto distribution need to be added to R with an additional
package?

Sort answer, yes:

I see it in the actuar and the VGAM packages that I have installed,  
but a more complete list of options would be from this search:
