[R] Plot step function
Hi, I am just starting to learn R, sorry for asking a simple question. How can plot a line x <= 0 y = 0, x > 0 y = 1? Thank you. - j [[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.
Re: [R] [FORGED] Plot step function
Thank you for the all response, how can the point y (0.0) on the same x axis, and X increases 1 between [-4, 4]?

Re: [R] [FORGED] Plot step function
Thanks Jim, that was I did to generate graphic from plot(c(-4,0,4),c(0,1,1),type="s",xlab="x",ylab="y"), it displayed [-4, -2, 0, 2, 4] in X, I tried to twist it, but could not get [-4, -3, -2, -1, 0, 1, 2, 3, 4] in X. Also, that the y 0.0 is above the X axis. I guess I try to figure out if, in general, there are parameters to define Δx (i.e Δx= 1), and to define [0, 0.0] at the joint of x axis and y axis. But never mind, if it is too much to ask :-). Thank you and greatly appreciate kind responses. - j On Mon, Feb 8, 2016 at 8:19 AM, Jim Lemon wrote: > Hail Jupiter, > Might a slight alteration of Rolf's suggestion do the trick? > > plot(c(-4,0,4),c(0,1,1),type="s",xlab="x",ylab="y") > > Jim > > On Sun, Feb 7, 2016 at 8:49 AM, jupiter wrote: > >> Thank you for the all response, how can the point y (0.0) on the same x >> axis, and X increases 1 between [-4, 4]? >> >> On Sun, Feb 7, 2016 at 5:29 AM, Rolf Turner >> wrote: >> >> > On 07/02/16 01:11, jupiter wrote: >> > >> >> Hi, >> >> >> >> I am just starting to learn R, sorry for asking a simple question.

Re: [R] [FORGED] Plot step function
Thanks Jeff, I've already added color and lwd to make it visible. I know it is not the optimal thing to do, but I was required. Cheers.

[R] Anova
Hi all, I apologize for what might be a silly question. I am interested in doing a one way anova. This is not too hard in and of itself, either with anova, aov or oneway.test . However, I need to 1) get pvalues, 2) do a posthoc analysis with Tukey HSD, 3) and have (sometimes) an unbalanced design. I just can't seem to put all the pieces together. Any suggestions?
