vertical semi-circles in R
Dear useRs, I am to teach my students some drawing techniques in R. I started shape of an handle by using the following codes; >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) The coding will draw a section of a handle. Now I want to draw semi circles of radius 0.05
