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 between (0,0.6) and (0,0.1), oriented vertically and outward with mouth facing against the y-axis. I tried every help available online but to no use. Thanks in advance, EB [[alternative HTML version deleted]]
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, mid = c(0,0.35), from = pi/2, to = -pi/2)
Note: you say you've tried every online help with no success. I had
never used package shape, at an R prompt I typed
> ?circle
No documentation for ?circle? in specified packages and libraries:
you could try ???circle?
so I tried ??circle and found the package. The rest took me less than 10
minutes. (Less than 5?)
Hope this helps,
Rui Barradas

I forgot to mention that a circle with radius 0.05 cannot go from (0,0.6) to (0,0.1), that's why I've changed the radius to 0.25, half the distance between those points. I also chose the center point.

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 <eliza_botto1 at outlook.com> wrote:> Dear useRs, > > > I am to teach my students some drawing techniques in R.
