Dear Grooup kindly
how can I plot these graphs in R.. Suppose that X is a discrete random variable with P(X = 0) = .25, P(X = 1) = .125, P(X = 2) = .125, and P(X = 3) = .5. Graph the frequency function and the cumulative distribution function of X. my solution was: x=c(0,1,3) px=c(.25,.125,.5) plot( x,px ,type="h" ) # to plot the frequency , is it correct how to plot the cdf? thanks in advance Ragia [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
