Re: [R] Intersection between circle and line?

Thanks! In principle it is a mathematical problem. I have already found some solutions with google. I thought there is maybe an existing R function or package which handel this stuff. But it seems not to be. sos package gives me no suitable information for that. With best regards -- View this

[R] Intersection between circle and line?

Dear R users, I am thinking about an easy and especially fast solution to calculate the x,y coordinates of the interesection between the borders of the red circle and the line. short example: plot(c(-3,0,3,9,21),c(-8,0,5,12,25)) draw.circle(0,0,radius=6,border=red,col=NA,lty=1,lwd=1) x -
