Re: [R] vertical semi-circles in R

Hi Eliza, How about this: library(plotrix) plot(0,type="n") draw.arc(rep(0,6),seq(0.1,0.6,by=0.1),radius=0.05, angle1=3*pi/2,angle2=5*pi/2) Jim On Sun, Jun 25, 2017 at 9:34 PM, Eliza B wrote: > Dear useRs, > > > I am to teach my students some drawing techniques in R. I started shape of an > h

Re: [R] vertical semi-circles in R

Hello, I'm not the greatest graphics programmer but is this it? #install.packages("shape") library(shape) # for function plotcircle plot(0,0,col="white") segments(0,0,0.3,0.3) segments(0.3,0.4,0.3,0.3) segments(0.3,0.4,0,0.7) segments(0,0.7,0,0.6) segments(0,0.0,0,0.1) plotcircle(r = 0.25, m
