Thank you for your reply! When I copy and paste the code into the Console, I receive several errors!
1) Error in plot(x, y, type = "n") : object 'x' not found > segments(x[-length(x)],y[-length(x)],x[-1],y[-length(x)]) Error in segments(x[-length(x)], y[-length(x)], x[-1], y[-length(x)]) : object 'x' not found 2)Error in points(x[-length(x)], y[-length(x)], pch = 16) : object 'x' not found points(x[-1],y[-length(x)],pch=1) 3) Error in points(x[-1], y[-length(x)], pch = 1) : object 'x' not found. What am I doing wrong? :'( -- View this message in context: http://r.789695.n4.nabble.com/How-to-plot-this-simple-step-function-tp4655792p4655813.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list 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.
