Re: [R] Intercept between two lines

Thank you Jorge, this did get me started and who else might be interested in the topic, a possible code could be something like: # Define the functions f1 <- function(x) 100-0.5*x f2 <- function(x) 150- x # Plot the functions par (xaxs="i", yaxs="i") plot(

You could also use polyroot. Do x0=Re( polyroot( c(100,-0.5) - c(150,-1) ) ) In your code. -- View this message in context: http://r.789695.n4.nabble.com/Intercept-between-two-lines-tp4587343p4589349.html Sent from the R help mailing list archive at Nabble.com. __

Hi pannigh, The following might get you started: > x0 <- uniroot(function(x) 100-0.5*x - (150- x), c(0, 150))$root > x0 [1] 100 > 100- 0.5*x0 [1] 50 HTH, Jorge.- On Wed, Apr 25, 2012 at 1:01 PM, pannigh <> wrote: > Dear List, > I know this is not the first post on this topic, but I need basic
