Hello Dear, I am trying to plot a function to see a minimum point (actually, using "optim"). For example, 1. y=f(x) 2. x has a range 3. plot(x,y) to see a point x minimizing y I tried "plot(x,y)", but it made an error. Am I doing a right way? Thanks, Jin -- View this message in context: http://n4.nabble.com/plotting-a-function-tp1747312p1747312.html Sent from the R help mailing list archive at Nabble.com.
