[ Please keep me in CC as I'm not subscribed to the list] Hi all, I?m new to R programming. Can someone help me , how to plot the ?y? for the following equations in ?R?? ?= ??5(??0.3)2+0.5 ??100(??0.5)2+0.5 ??100(??0.75)2 ?=28??+10?4?5?9+6?11 Also, I want to extract 50 random points from the function and add normally distributed noise to the data points to get ?noisy data?, ??. How to achieve this? Is there a function to fit polynomial of degree 5 to the noisy data? Thanks,
This looks like homework. This list has a *no homework* policy. There are extensive R tutorials on the web (and even the Intro to R shipped with the distro). Study them before asking us to do your work for you. See the posting guide linked below for what is expected of posters here.

Oh ... and don't cross post.

This looks like homework. There is a clearly-stated no-homework policy in the Posting Guide. Some hints though (typing a question mark before a function name in the console shows the help file for that function): - Generate some x values (?seq) - Calculate y values using x - plot x against y (?plot) - fitting can be done many ways, but the most common is using the ?lm function to fit and the ?predict.lm function to obtain points on the fitted equation.
